Abstract
A series of four new copper(II) complexes [Cu(H2L)(L1)] 1, [Cu(H2L)(PMDT)] 2, [Cu(H2L)(Dien)] 3 and [Cu(H2L)(L2)] 4 have been synthesized by template condensation (H2L=thiodiglycolic acid, L1=N-[(1)-1-(4-methylphenyl)ethylidene]benzohydrazide, PMDT=N,N,N′,N′,N ′′-pentamethyldiethylene- triamine, Dien=diethylenetriamine L2=N-[(1)-pyridin-2-ylmethylidene]benzohydrazide). The bonding and stereochemistry of the complexes have been characterized by molar conductance, elemental analysis, magnetic susceptibility, infrared, UV–visible, electron paramagnetic resonance structural studies and electrochemical studies. g-Values were calculated for all complexes in polycrystalline form as well as in DMSO solution. The magnetic and spectral data indicate square pyramidal geometry for 1 and octahedral geometry for 2–4 complexes. Cyclic voltammograms for all the complexes are similar and involve two irreversible redox processes. Their biological properties have also been studied. The thio complexes show more antibacterial activity than the controlled one. The antibacterial activities of the compounds have also been tested against Escherichia coli with different concentrations.
