Some Oxime and Amide Complexes of NiCl2

Abstract
[Ni(Aox)4Cl2] (Aox = acetaldoxime), [Ni(Acm)4(H2O)2]Cl2 (Acm = acetamide), Ni(Cy)3Cl2 (Cy = cyclohexanone oxime), and [Ni(cap)6]Cl2(Cap = caprolactam) have been prepared. Their solution electronic spectra indicate approximately octahedral environments for Ni(II) while solid Ni(Aox)4Cl2 shows a small tetragonal distortion. The i.r. spectra can be accounted for by oxime bonding to Ni via nitrogen and amide bonding to Ni via oxygen alone.
