Abstract

The adducts CuCl2·(3amt), CuCl2·2(3amt) ·2H2O, CuCl2·3(3amt), CuCl 2·(4amt), CuCl2·2(4amt), CuCl 2·3(4amt)·2H2O, CuCl2· (2mct)·H2O, CuCl2·2(2mct)·2.5H 2O, CuCl2·3(2mct)·2H2O, CuCl 2·(2mcp) and CuCl2·2(2mcp)·H 2O, where 3-amino-1,2,4-triazole = 3amt, 4-amino-1,2,4-triazole = 4amt, 2-mercaptothiazoline = 2mct and 2-mercaptopyridine = 2mcp, were synthesized by a solid state route and characterized by CHN elemental analysis and infrared spectroscopy. A thermogravimetric study was also performed. It was verified that 4amp is a molecule with a higher ability to act as a bridging ligand in comparison with 3amp. It was also found that, for all compounds, the mono adducts were the most thermally stable ones. Such a fact is in agreement with a higher ionic and covalent character of the metal-ligand bond in surch compounds.
