Abstract
Sulpha drugs have served as potential antimicrobial agents from ancient days and many new drugs were synthesized along with organic and metal hybrids. In this present work synthesized novel thiosemicarbazone ligands, 2- hydroxybenzaldehyde-4-(4'-(4-aminophenyl)sulfonylphenyl)-3-thiosemicarbazone, 2-hydroxy-benzaldehyde-4-(4'-(4(2-hydroxybenzylidene)aminophenyl)sulfonylphenyl)-3-thiosemicarbaz-one, 2-hydroxybenzaldehyde-4-(4'-(4(thiophene-2-ylmethylene)- aminophenyl)sulfonylphenyl)-3-thiosemicarbazone and 2-hydroxy-benzaldehyde-4-(4'-(4(3,4-dimethoxybenzylidene)-aminophenyl)sulfonylphenyl)-3-thiosemicarbazone derived from 4,4'-sulfonyldianiline, and its cobalt and copper complexes. All synthesized compounds were characterized using elemental analysis, FT-IR, 1H NMR, 13C NMR, mass spectra, magnetic moment and molar conductance measurements and thermal analysis. The electrochemical properties such as anodic, cathodic peak potential and electron transfer process of the complexes were studied using CV measurements. All compounds were efficiently synthesized in good yields in ranges of 74–88% and screened for their antimicrobial potentials. Results were compared with standard antibacterial (Ciprofloxacin) and antifungal (Nystatin) which served as controls. The molar conductance data revealed that the chelates were non-electrolytes. From the spectral and magnetic moment data the complexes were found to have octahedral geometry
