The results of the structural and electronic structure of p-cyanobenzenosulfonamide (L), and its copper(II)complex, Cu(L)2(NH3)2 are reported. Both compounds have been prepared and their crystal structuresdetermined. The sulfonamide crystallizes in the orthorhombic system, space group, Pnma and Z = 4,whereas the complex crystallizes in the triclinic system, P-1 and Z = 2. The coordination geometry ofthe copper(II) ion in the complex can be described as a distorted square planar with two N-sulfonamideand two NH3 in opposite vertices. The thermal behavior of both, the ligand and the Cu(II) complex, wasinvestigated by thermogravimetric analyses (TG) and differential thermal analysis (DT). The experimentalIR, Raman and UV?VIS spectra have been assigned on the basis of DFT calculations. 2012 Elsevier B.V. All rights reserved.
