Abstract:

<p> A series of Co(II), Ni(II), Cu(II), and Zn(II) complexes of quinoline-thiosemicarbazones was prepared. The Schiff base ligands that provide N, O, and S donor atoms for ligation are synthesized by the condensation of 2-hydroxy-3-formylquinoline with substituted thiosemicarbazides in ethanol. The ligands and complexes are characterized by elemental analysis, infrared, 1H NMR, UV-Vis, fast atom bombardment (FAB) mass spectroscopy, and electron spin resonance (ESR) spectral studies followed by magnetic susceptibility and conductivity measurements. The ligand-to-metal ratio is found to be 1:1 and 2:2 for the complexes of L1H2 and L2H2, respectively. All the complexes are found to have octahedral geometry except [CuL1H(H2O)Cl], which exhibits a square pyramidal structure. All the complexes are nonelectrolytic in nature and the electrochemical behavior of complexes is dealt with briefly. Further ligands and complexes were evaluated for their antimicrobial activity against bacteria Escherichia coli and Pseudomonas aeruginosa and fungi Aspergillus niger and Cladosporidium.</p>
