A series of new N-sulfonamidate ligands and their cooperai) complexes, [Cu(N-(5-ethyl-[ 1,3,4]-thiadiazole-2-yl)-toluenesulfonamidate) 2(py)2(H2O)](H2O) (1) and [Cu(N-(5-ethyl-[1,3,4]thiadiazole-2-yl)-benzenesulfonamidate) 2(py)2(H2O)] (2) have been synthesized and characterized. The X-ray crystal structures of the complexes 1 and 2 have been determined. In the both two complexes, the Cu2+ ion is five-coordinated, forming a CuN4O chromophore. The ligands act as monodentate, coordinating the metal ion through a single Nthiadiazole atom. The molecules from the reaction medium (pyridine and water) also participate to the coordination of Cu2+ ion as monodentate ligands. Both two complexes have a slightly distorted square pyramidal geometry. The chemical properties of the complexes have been studied by FT-IR, electronic and EPR spectroscopic methods.
