Polynuclear paddle-wheel copper(II) propionate with di-2-pyridylamine or 1,10-phenanthroline: Preparation, characterization and X-ray structure

The synthesis, spectroscopic, magnetic and structural characterization of two new polynuclear copper(II) propionate are described. Both compounds exhibit the typical paddle-wheel type structure. The complex [Cu4(dpyam)2(OCOC2H5)2(mu-O2CC2H5)6(H2O)2][Cu2(mu- O2CC2H5)4(H2O)2] ¡¤ (DMF)2 1; where dpyam = di-2-pyridylamine, the “outer” Cu ions, with a CuN2O2O? chromophore, have an intermediate five-coordinate geometry. The “inner” Cu ions, with a CuO4O? chromophore, have a square pyramidal geometry. The two Cu(II) ions in the inner unit are bridged by four syn,syn-eta1:eta1:mu propionates, showing the paddle-wheel cage type. The “outer” and “inner” linked by propionate bridges showing syn,anti-eta1:eta1:mu coordination mode. The 1D structure of complex [Cu6(phen)2(H2O)2(mu-O2CC2H5)12]n[Cu2(mu-O2CC2H5)4(H2O)2]2n ¡¤ (H2O)0.5n 2; where phen = 1,10-phenanthroline, consists of zig-zag chains of mononuclear Cu(mu-O2CC2H5)2(H2O)(phen) repeating units running along the b-axis, which are connected along the unit cell diagonal via Cu2(mu-O2CC2H5)4 paddle-wheel dinuclear units. Within mononuclear and dinuclear units, the Cu(II) ions have a square pyramidal geometry. However, the outer sphere of both compounds consists of the Cu2(mu-O2CC2H5)4(H2O)2 paddle-wheel molecule in which Cu(II) ions involve a square pyramidal geometry.

A BODIPY derivative for colorimetric fluorescence sensing of Hg2+, Pb2+ and Cu2+ ions and its application in logic gates

A BODIPY-based colorimetric and fluorescent chemosensor 1 anchored with dipyridylamino (DPA) receptor has been designed, synthesized and characterized. It exhibited a simultaneous sensitive recognition for Cu2+, Hg2+ and Pb2+ ions. With the addition of these three kinds of metal ions into 1 in CH3CN, its initial absorption maximum displayed obvious blue shifts, and the color changes of the solution could be clearly observed by naked eyes. Besides, the fluorescence intensity was significantly enhanced accompanied with the appearance of new emission peaks at 587 nm for Pb2+ and Hg2+ ions and 545 nm for Cu2+ ions. These results were attributed to the pi-deconjugation between N-pyridyl and the BODIPY group due to the binding of metal ions with the BODIPY and DPA groups. Based on the sensing behaviors of 1, three logic gates (OR, INHIBT and combinational logic gate) were constructed correspondingly.

Novel building units with bimetallic rings in inorganic/organic hybrid chains and layers

Hydrothermal synthesis has produced three new compounds constructed from novel building units containing vanadium-oxide (or oxyfluoride) subunits linked together via covalently bound cationic copper complexes. Each new compound exhibits novel structural features: [Cu(dipa)][VOF4] (1) incorporates a corner-sharing octahedral vanadium(IV) oxyfluoride chain decorated by copper-(2,2?-dipyridyl amine) complexes which form intra-chain bridges. Within a similar reactant system [Cu(dipa)]2[V6O17] (2) is produced, the structure of which exhibits edge-sharing trigonal bipyramidal vanadium(V) ‘ladder-like’ double chains which are bridged into layers by tetrahedral pyrovanadate dimers together with the copper-(2,2?-dipyridyl amine) complexes. [Cu(py)4]2[V4O12] (3), is a 2-D structure featuring exclusively tetrahedral vanadium(V) in four-membered ring building blocks, linked through octahedral copper-pyridine complexes to form two crystallographically different bimetallic layers.

Study of new mononuclear platinum group metal complexes containing eta5 and eta6 – Carbocyclic ligands and nitrogen based derivatives and formation of helices due to NH?Cl interactions

A quite general approach for the preparation of eta5- and eta6-cyclichydrocarbon platinum group metal complexes is reported. The dinuclear arene ruthenium complexes [(eta6-arene)Ru(mu-Cl)Cl] 2 (arene = C6H6, C10H14 and C6Me6) and eta5- pentamethylcyclopentadienyl rhodium and iridium complexes [(eta5- C5Me5)M(mu-Cl)Cl]2 (M = Rh and Ir) reacts with two equivalents of the ligands 2-chloro-3-(pyrazolyl)quinoxaline (L 1) and di-(2-pyridyl)amine (L2) in presence of NH 4PF6 to afford the corresponding mononuclear complexes of the type [(eta6-arene)Ru(L1)Cl]PF6 {arene = C6H6 (1), C10H14 (2) and C 6Me6 (3)}, [(eta6-arene)Ru(L 2)Cl]PF6 {arene = C6H6 (4), C 10H14 (5) and C6Me6 (6)}, and [(eta5-C5Me5)M(L1)Cl]PF 6 {M = Rh (7), Ir (8)} and [(eta5-C5Me 5)M(L2)Cl]PF6 {M = Rh (9), Ir (10)}. However the mononuclear eta5-cyclopentadienyl analogues such as [(eta5-C5H5)Ru(PPh3) 2Cl], [(eta5-C5H5)Os(PPh 3)2Br], [(eta5-C5Me 5)Ru(PPh3)2Cl] and [(eta5-C 9H7)Ru(PPh3)2Cl] complexes react in presence of one equivalent of ligands 2-chloro-3-(pyrazolyl)quinoxaline (L 1) and di-(2-pyridyl)amine (L2) and one equivalent of NH4PF6 in methanol yielded mononuclear complexes [(eta5-C5H5)Ru(PPh3)(L 1)]PF6 (11), [(eta5-C5H 5)Os(PPh3)(L1)]PF6 (12), [(eta5-C5Me5)Ru(PPh3)(L 1)]PF6 (13) and [(eta5-C9H 7)Ru(PPh3)(L1)]PF6 (14) and [(eta5-C5H5)Ru(PPh3)(L 2)]PF6 (15), [(eta5-C5H 5)Os(PPh3)(L2)]PF6 (16), [(eta5-C5Me5)Ru(PPh3)(L 2)]PF6 (17) and [(eta5-C9H 7)Ru(PPh3)(L2)]PF6 (18) respectively. These compounds have been systematically characterized by IR, NMR and mass spectrometry. The molecular structures of 2, 4 and 15 have been established by single crystal X-ray diffraction study and some of the representative complexes have also been studied by UV-visible spectroscopy. The crystal packing diagram of complex 4 reveals that the cation [(eta6-C6H6)Ru(L2)Cl]+ is engaged in non-covalent interaction. This compound gives rise to a 1D helical architecture along the ‘a’ axis via intermolecular NH?Cl hydrogen bonds.

Hydridodimethylplatinum(IV) complexes with bis(pyridine) ligands: Effect of chelate ring size on reactivity

The effect of changing the bite angle of the dipyridyl ligand LL on the reactivity of the dimethylplatinum-(II) complexes [PtMe2(LL)] has been studied, by comparing complexes with the ligands LL = di-2-pyridylamine (DPA) or di-2-pyridyl ketone (DPK), which form a six-membered chelate ring, to compounds with 2,2?-bipyridyl derivatives, which form a five-membered chelate ring. The complex [PtMe2(DPA)] undergoes easy oxidative addition of methyl iodide to give the corresponding platinum(IV) complex [PtIMe3(DPA)]. Both [PtMe2(DPA)] and [PtMe 2(DPK)] are protonated by acids HX at low temperature to give the hydridodimethylplatinum(IV) complexes [PtHXMe2(NN)] and [PtH(S)Me2(NN)]X (S = solvent), which can exist in two isomeric forms with H trans to X or N. The structure of the complex [PtHClMe2(DPK)] was determined crystallographically. In a solution containing excess CD 3OD, extensive hydrogen/deuterium exchange occurs into the methylplatinum groups and methane product at low temperature, indicating very easy reversibility of the exchange between hydridomethylplatinum(IV) and (methane)platinum(II) complexes. The hydridomethylplatinum(IV) complexes reductively eliminate methane at room temperature in solution but have significantly higher thermal stability and undergo more extensive H-D exchange than when NN = 2,2?-bipyridyl. The reaction of [PtMe2(DPA)] with excess HCl gave [PtCl2(DPA)], and the reaction of [PtMe 2(DPK)] with excess CF3SO3H gave the aqua complex [Pt(OH2)2(DPK)](CF3SO3) 2 or the binuclear hydroxo complex [Pt2(mu-OH) 2(DPK)2](CF3SO3)2, depending on the experimental conditions.

Coordination geometries in bis(di-2-pyridylamine)copper(II) complexes

The crystal structures of three compounds containing bis(di-2-pyridylamine)copper(II) complex units have been determined by X-ray crystallographic methods; [Cu(dpyam)2(OH2)2](S4O 6) (1), [Cu(dpyam)2(CF3SO3)2] (2) and [Cu(dpyam)2(SO4)]2[Cu(dpyam)2 (OH2)2](PF6)2¡¤2H 2O (3). In compound 1 the anions are uncoordinated, and each Cu(II) ion involves the elongated tetragonal octahedral geometry with two water molecules occupying the axial positions. Compound 2 consists of neutral mononuclear units, the Cu(II) environment being elongated tetragonal octahedral with two unidentate triflate anions coordinating in axial positions. Two crystallographically independent molecules are found in compound 3, one complex unit being centrosymmetric and octahedrally elongated, with two water molecules coordinated in the axial positions, the other predominately close to the distorted square-based pyramidal (4 + 1) stereochemistry of the CuN3ON? chromophore which is best described as square-pyramidal cis-distorted octahedral (4 + 1 + 1*). The latter complex unit of compound 3 is the first example containing a cis-distorted octahedral coordination among the copper(II) complexes with divalent oxyanions.

Immobilisation of eta3-allyldicarbonyl complexes of Mo II with bidentate nitrogen ligands within aluminium-pillared clays

Molybdenum(II) complexes [MoX(CO)2(eta3-allyl) (CH3CN)2] (X = Cl or Br) were encapsulated in an aluminium-pillared natural clay or a porous clay heterostructure and allowed to react with bidentate diimine ligands. All the materials obtained were characterised by several solid-state techniques. Powder XRD, and 27Al and 29Si MAS NMR were used to investigate the integrity of the pillared clay during the modification treatments. 13C CP MAS NMR, FTIR, elemental analyses and low-temperature nitrogen adsorption showed that the immobilisation of the precursor complexes was successful as well as the in situ ligand-substitution reaction. The new complex [MoBr(CO)2(eta 3-allyl)(2-aminodipyridyl)] was characterised by single-crystal X-ray diffraction and spectroscopic techniques, and NMR studies were used to investigate its fluxional behaviour in solution. The prepared materials are active for the oxidation of cis-cyclooctene using tert-butyl hydroperoxide as oxidant, though the activity of the isolated complexes is higher. Wiley-VCH Verlag GmbH & Co.

Influence of a halide ion on ribbons of water pentamer

Reactions of CuF2, CuCl2 ? 2H2O and CuBr2 with 2,2?-dipyridylamine (HDPA) in water at room temperature using Cu:HDPA = 2:1 mol yield [Cu(HDPA)(H2O) 2F]F ? 3H2O (1), Cu(HDPA)Cl2 (2) and Cu(HDPA)Br2 (3) respectively. The structures of 2 and 3 are isostructural in spacegroup C2 with cell dimensions; for 2, a = 14.702(8), b = 7.726(2), c = 4.829(6) A, beta = 96.68(8) and for 3, a = 14.2934(8), b = 7.9057(6), c = 5.1982(5) A, beta = 94.049(7). In the X-ray crystal structure, the complex 1 is found to contain tapes of water pentamers. Our DFT calculations at the B3LYP/LanL2DZ level show that the reaction Cu(HDPA)X2 + 2H2O = [Cu(HDPA)(H 2O)2X]X is most exothermic in the gas phase when X – = F-, i.e., the tendency of water uptake is maximum for Cu(HDPA)F2. It seems that the exothermicities of the aquations of Cu(HDPA)Cl2 and Cu(HDPA)Br2 are not sufficient to stabilise the type of ribbons of water observed in 1 and consequently water is eschewed when X- = Cl- or Br-. Cu(2,2?-dipyridylamine)X2 takes up water to produce ribbons of water pentamer, as shown in the accompanied picture (red: O atom of a solvent water molecule), only when X- is F- but not when it Cl- or Br-. The results are rationalised by means of DFT calculations at the B3LYP/LanL2DZ level. [Figure not available: see fulltext.]
