Ligand-bridged bicobaloximes synthesized by ligand replacement: Synthesis, structure and characterization

Two ligand-bridged bicobaloximes, formed by replacement of pyridine (py) in monocobaloximes, [MeCo(dmgH)2(py)] (Me = methyl, dmgH = dimethylglyoxime) and MeCo(dpgH)2(py) (dpgH = diphenylglyoxime), by 4,4′-bipyridine and 2,4-di(1H-imidazol-1-yl)-6-methoxy-1,3,5-triazine, respectively, are reported. The crystal structures of the ligand-bridged bicobaloximes so obtained are described.
