A Schiff base (E)-4-(4-methoxybenzylideneamino)-N-(5-methylis-oxazol-3-yl) benzene-sulfonamide (C18H17N3O4S), and its copper complex were synthesized and the structures elucidated in the bases of elemental analysis, 1HNMR, UV–VIS, IR, Mass spectroscopy, magnetic susceptibility, thermal analysis and conductance measurements. The studies indicate an octahedral structure for the complexes with the (C22H27N3O10SCu) formula. The I.R. spectra suggest that the ligand acts as a tridentate (NNO) donor. Also, the biological activity of the Schiff base and its Cu complex are biologically active.
