Abstract

Cobalt(II), nickel(II), and copper(II) complexes with acetaldehyde oxime and benzaldehyde oxime have been prepared and characterized by vibrational and electronic spectroscopy, magnetism, and other methods. The cobalt(II) and nickel(II) complexes isolated are of the general formulae: (A) MX2(oxime)4 (X=Cl, Br, I, NO3, NCS and CH3COO); (B) M(NCS)2(oxime)2; (C) MSO4 (oxime)3·3H2O. They are all six-coordinate, and the complexes (B) are probably multinuclear. Copper(II) forms complexes of the formulae: (A) CuX2(oxime)4 (X=Cl, Br), (B) CuX2(oxime)2 (X=Cl, Br, NCS); (C) CuSO4(oxime)H4·H2O. Possible structures for these copper(II) complexes are also discussed. Acetaldehyde oxime and benzaldehyde oxime are unidentates in all these complexes, being coordinated through their nitrogen atom.
