Abstract
A series of new binucleating CoII, NiII, CuII, and ZnII complexes of bicompartmental ligands with SNO donors was prepared. The Schiff bases were obtained by the condensation of 4,6-diacetylresorcinol and mercapto-substituted 1,2,4-triazoles. The ligands and their complexes were characterized by elemental analysis, infrared, 1H-NMR, UV-Vis, FAB-mass, and ESR spectral studies, magnetic susceptibility, and conductivity measurements. All the complexes were monomeric and binuclear. NiII and CoII complexes were octahedral, whereas CuII and ZnII complexes were square planar and tetrahedral, respectively. The compounds are investigated for electrochemical activity.
