New Synthetic Routes to Face-to-face and Open-book Triazenide-bridged Dirhodium Bipyridyl Complexes with the (4+) Core
The iodide-abstraction reaction of <2>2 1 (bipy = 2,2′-bipyridyl, R = p-tolyl) with AgPF6 in MeCN gave 2 2 which slowly decarbonylated at room temperature to 2 3.The crystal structure of 3 shows a Rh-Rh single bond <2.534(2) Angstroem> and one of the three terminal nitrile ligands axially attached to the bipy-bound rhodium atom.Complex 3 reacts with Na*2H2O to give 4.In CH2Cl2, the iodide-abstraction reaction of 1 affords a green solution containing a carbonyl complex (2+) A (solv = CH2Cl2), an analogue of 2.Complex A (solv = CH2Cl2) reacted with neutral chelating lgands to give the carbonyl-bridged complexes 2 the last of which undergoes reduction with NaBH4 to give paramagnetic 11 having a face-to-face structure with a monodentate dppe ligand.With Ph2PCH2PPh2 (dppm), A (solv = CH2Cl) afforded 2 10a X-ray studies on which, as a CH2Cl2 solvate, reveal a carbonyl-bridged open-book structure with a Rh-Rh distance of 3.179(2) Angstroem and a large Rh-C(O)-Rh angle of 108.3 deg.Complex 10a equilibrates with the face-to-face, terminal carbonyl isomer 2 10b in solution.The electronic structures of the two isomers have been probed by extended-Hueckel molecular-orbital calculations on the model compound .These show (i) the absence of metal-metal bonding in 10a while 10b has a Rh-Rh ? bond, and (ii) that the CO in 10a is best viewed as more ketonic than a typical bridging carbonyl.The reaction of complex A (solv = CH2Cl2) with neutral chelating ligands also gives low yields of <2> 12 the crystal structure of which shows two dirhodium fragments linked by two O2PF2 groups bridging across axial and equatorial sites in different (4+) moieties.The reaction of A (solv = CH2Cl2) with N-SH ligands yields (N-S = 1-methyl-2-sulfanylimidazolate 13, 2-sulfanylpyrimidinate 14, 2-sulfanylthiazolinate 15, or 2-sulfanylbenzimidazolate 16), and NaX gives (X = Cl or NO2).
