Summary

Divalent cobalt, nickel, copper, zinc, cadmium and mercury salts react with 4-benzamido-1-diacetylmonoxime-3-thiosemicarbazone (BDTS) forming two types of complexes,i.e., [M(BDTS)X2 · nH2O]YH2O (M = CoII, NiII, ZnII, CdII or HgII; X = Cl, Br or 1/2 SO4 and n=0–1) and [Cu(BDTS)X]2 · nH2O (X=Cl, Br or 1/2 SO4 and n=0–1). The complexes were identified and characterized on the basis of partial chemical analysis, molar conductance, magnetic moment and spectral (visible, n.m.r., i.r.) studies. I.r. spectral studies suggest that BDTS is tridentate and coordinatesvia the azomethine groups (hydrazone and oxime residue) as well as the thioketo-group with cobalt and nickel but is bidentate coordinatingvia the azomethine groups with the remaining metal ions. Further, the ligand behaves as a reducing agent towards CuII salts forming diamagnetic CuI complexes.
