Binary Pd-polyoxometalates [Pd(dpa)2]3[PW 12O40]2×12 DMSO (2), [Pd(dpa) 2]3[PMo12O40]2×12 DMSO×2 H2O (3), and [Pd(dpa)(DMSO)2] 2[HPMo10V2O40]×4 DMSO (4) were synthesized by reaction of [Pd(dpa)(OAc)2]×2 H2O (1; dpa=2,2?-dipyridylamine) with three Keggin-type polyoxometalates and fully characterized by single-crystal and powder XRD analyses, IR spectroscopy, and elemental analyses. The synthesis is facile and straightforward, and the complicated ligand-modification procedure often used in the traditional charge-transfer method can be omitted. In 2-4, Pd complexes and polyoxometalate anions are coupled through electrostatic interaction. Compound 4 is more active than the other three compounds in the selective aerobic oxidation of alcohols at ambient pressure. Interestingly, during catalytic recycling of compound 4, unprecedented ternary Pd-V-polyoxometalate [Pd(dpa)2{VO(DMSO) 5}2][PMo12O40]2×4 DMSO (5), which was captured and characterized by single-crystal XRD, proved to be the true active species and showed high catalytic activity for the selective aerobic oxidation of aromatic alcohols (98.1-99.8 % conversion, 91.5-99.1 % selectivity). Moreover, on the basis of control experiments and EPR and UV/Vis spectra, a plausible reaction mechanism for the oxidation of alcohols catalyzed by 5 was proposed. Binary noble metal-POM compounds: The unprecedented ternary Pd-V-POM compound (POM=polyoxometalate) [Pd(dpa)2{VO(DMSO) 5}2][PMo12O40]2×4 DMSO, which was isolated during the catalytic recycling of [Pd(dpa)(DMSO) 2]2[HPMo10V2O40]×4 DMSO (dpa=2,2?-dipyridylamine) and characterized by single-crystal X-ray diffraction, proved to be the true active species and showed high catalytic activity for the aerobic oxidation of aromatic alcohols (see figure).

The controlled crystallization of specific tantalum oxide-fluoride and tantalum fluoride anions ([TaOF5]2-, [TaF 6]-, and [TaF7]2-) is demonstrated using organic reagents with varied corresponding pKa values in the presence of aqueous hydrofluoric acid. The identity of tantalum oxide-fluoride or fluoride anions of [TaOF5]2-, [TaF6] -, and [TaF7]2- are shown to crystallize successively from solution to solid state by increasing the corresponding pKa of organic reagents, which lead to the subsequent increase of fluoride concentration in the hydrofluoric acid solution. With the use of this methodology, three new hybrid crystal structures were targeted: [H 2(2,2?-bpy)]TaOF5 (2,2?-bpy = 2,2?-bipyridyl) 1, [Hdpa]TaF6 (dpa = 2,2?-dipyridylamine) 2, and [H2En]TaF7 (En = ethylenediamine) 3, respectively. The applicability and comparison of this methodology for tantalum and previously prepared niobium compounds show that it can be broadly used to design new materials with specific functionalities for other transition metal oxide-fluorides.

We consider coordination compounds of ions with unfilled up 3d- and 4f-shell in a weak or intermediary crystalline field, containing dimer clusters in the case when the distance between clusters is more than the distance between the ions forming the cluster. In this case it is possible to neglect the exchange interaction between electrons of different clusters and the structure of the ground state of separate dimer is determined by the intercluster exchange, spin orbital, magnetic dipole?dipole, and hyperfine interactions. The presence of other dimers in the crystal is possible to take into account if populations of energy levels of system upon interacting dimer clusters are calculated.

In the title dinuclear acetate-bridged complex, [Cu2(C2H3O2)3(NCS)(C10H9N3) 2], the two Cu atoms are five-coordinated, with a basal plane consisting of two N atoms of a di-2-pyridylamine (dpyam) ligand and two O atoms of two different acetate ligands. The axial positions of these Cu atoms are coordinated to N and O atoms from thio-cyanate and acetate mol-ecules, respectively, leading to a distorted square-pyramidal geometry with values of 0.30 and 0.22. Both Cu II ions are linked by an acetate group in the equatorial-equatorial positions and have syn-anti bridging configurations. Hydrogen-bond inter-actions between the amine H atom and the coordinated and uncoordinated O atoms of the acetate anions generate an infinite one-dimensional chain.

The dinucleating ligand, tpbpd (tetrapyridyl biphenylenediamine) forms a dicopper complex with practically no electronic coupling between the two copper (II) centres. The EPR spectrum of the complex is consistent with coordination of each copper ion to two nitrogens of the binuclear ligand. Cyclic voltammogram of the complex also reveals that the two copper (II) centres have identical ligating environment. This dimeric copper (II) complex is found to be a very efficient catalyst for the cleavage of plasmid DNA in the absence of any added cofactor. The amount of conversion of supercoiled form (Form I) of plasmid to the open circular form (Form II) depends on the concentration of the complex as well as the duration of incubation of the complex with DNA. The maximum rate of conversion of the supercoiled form to the nicked circular form at pH 7.5 in the presence of 150 muM of the complex is found to be 1.8 × 10-3 s-1.
