Bivalent metal complexes ofp-chloro-,p-methyl- andp-methoxybenzoylhydrazone oximes (H2BMCB, H2BMMB or H2BMTB=H2L), [M(H2L)Cl2]. nH2O (M=ZnII, CdII or HgII, n=0 or 1; [M(H2L)Cl2] (M=ZnII or CdII); [M(HL)2(H2O)n]. YH2O (M=CoII, CuII, ZnII or UVIO2, n=0–2); [Ni(H2BMCB)(H2O)3]Cl2, [Ni(BMMB)(H2O)]2 and [Ni(BMTB)(H2O)]2, were synthesized by conventional physical and chemical measurements. I.r. spectra show that the ligands are bidentate or tridentate. Spectral, magnetic and molecular weight measurements suggest that cobalt(II) and nickel(II) have monomeric octahedral geometry when derived from H2BMCB, a dimeric square planar geometry for nickel(II) and monomeric square planar geometry for cobalt(II) for those isolated from H2BMMB or H2BMTB. Also, a monomeric distorted octahedral structure is proposed for copper(II) complexes derived from the ligands under investigation.
