  Cobalt(III) Complexes of Dimethylglyoxime with No Direct Cobalt–Carbon Bond as Possible Non‐Organometallic Models for Vitamin B₁₂

  摘要：

  Cobaloximes of the type [CoX(HdMg)(2)B] [X = Cl, CN, SCN or 1, and B = py (pyridine), 4-aminopy (4-aminopyridine), or bipy (2,2'-bipyridine)], [CoCl2(Hdmg)B] [B = bipy and phen (1,10-phenathroline)], and [CoPF4(HdMg)(2)py] were synthesized and characterized by elemental analyses, melting points, solubility, conductivity, room temperature, magnetic susceptibility measurements, infrared and UV-VIS electronic spectra, and cyclic voltammetry. The complexes melted/decomposed at 220-314degreesC and, with the exception of a few, many of them dissolved only in coordinating organic solvents. The complexes are orange to brown. They are also non-electrolytes in organic solvents. The IR spectra indicated that the complexes coordinate through the N atom of the oxime group of each ligand. The magnetic susceptibilities and electronic spectra of the complexes indicated that they are low-spin d(6) octahedral. Electrochemical studies on some of the complexes, using cyclic voltammetry, revealed that some of the complexes underwent reversible oxidation-reduction and are, therefore, viable models for vitamin B-12. A variety of structures have been proposed for the complexes.
