  Abstract:  The paper reports the synthesis, physical and chemical characterization of two complexes with Cu(II) and N-substituted sulfonamide as ligands: [Cu(N-(5-ethyl-1,3,4-thiadiazol-2-yl)-4-methylbenzene-sulfonamidate)2(ethylenediamine)] (1) and [Cu(N-[5-(ethylsulfanyl)-1,3,4-thiadiazol-2-yl]benzenesulfonamidate)2(H2O)3] (2). The structures of complexes were confirmed by elemental analysis, IR, UV-Vis spectroscopy, magnetic measurements and electronic paramagnetic resonance (EPR) spectra. Correlations of the results obtained from physico-chemical investigations afford the assignment of the most probable structural formulae for the metal complexes. The ligands act as monodentate, coordinating the metal ion geometry through a single Nthiadiazole atom. The complex 1 present a square-planar and the complex 2 present a slightly distorted square pyramidal geometry.

Keywords: copper(II) complexes, sulfonamides N-substituted
