Abstract

AbstractThe preparation and characterization of some dipositive metal ion complexes derived from potassium 3‐(benzotriazole‐1‐carbonylmethyl)‐dithiocarbazate (BCDHK) is reported. The solid complexes of the composition ML · nH2O (M = Mn(II), Ni(II), Cu(II), Cd(II), Zn(II) and Co(II), n = 0,1) and ML2 · 2H2O (M = Pb (II), UO2(VI)), have been characterized on the basis of elemental analyses, IR, UV and TGA. IR spectral data indicate that BCDHK behaves as either a mononegative or binegative ligand and coordinates in a tridentate or bridging tetradentate manner.
