Cimetidine complexes derived from cobalt(II), nickel(II) and copper(II) salts of polyatomic anions

1986

Cobalt(II), nickel(II) and copper(II) complexes [M(CM)2]X2 (X = BF4 or NO3) have been prepared with cimetidine (CM). Powder data, molar conductivities, magnetic moments, i.r. and electronic spectra support apseudo-octahedral stereochemistry with MN2N 2 ⋆ S2 chromophore and tentative structures are proposed for the complexes. Their properties are compared with these of previously prepared complexes.
