Abstract

The preparation of 2-thiouracil (H2L) and its 5-(2-thiazolylazo)thiouracil(H2L') complexes with Co-II, Ni-II, Cu-II, Zn-II and Cd-II are reported. The new complexes have been characterized by elemental analyses, solid reflectance, infrared spectra and magnetic susceptibilities. These measurements suggest that, the ligand is bound to the metal ion through nitrogen and/or sulphur atom behaving as mono- or bidentate ligand. Thermal decomposition studies of these metal complexes are explained to give more information on the structure of the investigated chelates. On the basis of the nu (OH) bending frequencies and the insolubility of the complexes in common organic solvents, polymeric structures have been proposed. (C) 2001 Elsevier Science B. V.
