We report Li-I, Na-I, K-I, Pb-II, Co-II, Ni-II, Cu-II, Zn-II, Cd-II and Hg-II coordination compounds derived from thiabendazole [2-(4'-thiazolyl)benzimidazole (tbz)]. The compounds were characterised by analytical and spectroscopic techniques. NMR studies of diamagnetic compounds were performed in solution. X-ray diffraction analysis of Na-I, Pb-II, Co-II, Ni-II, Cu-II and Cd-II complexes showed that tbz stabilises bis- and tris-chelated coordination compounds. In solution and in solid state the ligand coordinates to the metal ions through the imidazolic and thiazole nitrogen atoms regardless of the nature of the metal ion. (C) 2002 Elsevier Science B.V.
