Abstract

A series of mixed ligand Salicylaldehyde phenyl hydrazine complexes with a general formula [ML1L2], where M = Mn(II), Co(II), Ni(II), and Cu(II), L1 = Salicylaldehyde phenyl hydrazine, and L2 = salicylaldehyde thiosemicarbazone have been prepared and characterized by elemental analysis, FTIR and UV spectroscopy, magnetic moment, and conductance analysis. The infrared spectra showed that symmetrical tridentate coordination occurred with the oxygen, nitrogen and sulfur atoms. The electronic spectra, elemental analysis, and magnetic moment results proved that the complexes adopted octahedral geometry. The conductance measurement showed that the complexes are non electrolytes proving their nonionic nature. The complexes were subjected for anti-microbial and anti –fungal screening.

Keywords: Mixed ligand complexes, phenyl hydrazine, salicylaldehyde and thiosemicarbazone.
