Cobalt(III), nickel(II) and copper(II) complexes of benzil-α-monoxime (BMO) have been synthesized and characterized by elemental analyses, Conductivity, magnetic susceptibility measurements, IR and electronic spectral data. The molar conductivity data show them to be non-electrolytes. The monoanionic bidentate behavior of BMO is inferred from IR spectral studies. The electronic spectral data suggest planar geometry for nickel(II) and copper(II) complexes. The nickel complex assumes an octahedral structure in a coordinating solvent (N,N-dimethylformamide (DMF)). The [Co(BMO)3] complex has been isolated as a single crystal and its structure was determined by X-ray diffraction. X-ray data confirms the presence of a fac-octahedral configuration for this complex. Electrochemical studies suggest that the cobalt complex undergoes two single one-electron reduction steps corresponding to Co(III) → Co(II) and Co(II) → Co(I). (C) 2000 Elsevier Science Ltd.

Chelates of Cr(III), Mn(II), Fe(III), Co(II), Ni(II) and Cu(II) ions with the bidentate ligand α-benzilmonoxime (α-BMOH) have been studied.On the basis of conductometric titrations, elemental analysis and molar conductivity data, the chelates have been assigned structures , 2>, , , and .Magnetic susceptibility and absorption and infrared spectra of the chelates are reported and discussed.The magnetic moment studies provide evidence for the existence of octahedral Cr(III) and Fe(III) complexes and square planar Co(II), Ni(II) and Cu(II) complexes.
