Binuclear and mononuclear cobalt(II), nickel(II) and copper(II) complexes of 4,4'-bis(alkylaminoisonitrosoacetyl)diphenyl-methane derivatives

摘要

4,4'-Bis(chloroacetyl)diphenylmethane has been prepared from ClCH_2COCl and Ph-2CH_2·4,4'-Methylenebis(phenylglyoxylohydroximoyl chloride has also been obtained. Four new substituted 4,4'-bis(alkylaminoisonitrosoacetyl)diphenylmethanes (ligands) have been prepared from 4,4'-methylenebis(phenylglyoxylohydroximoyl chloride) and the corresponding amines. The Ni~(II), Cu~(II) and Co~(II) complexes of these ligands were prepared and their structures were identified using AAS, i.r., ~1H-n.m.r. spectral data, elemental analyses and magnetic susceptibility measurements.
