Abstract

Some Pb(II) complexes of dibasic tridentate Schiff base ligands derived from aldehydes/ketones and benzoylhydrazine have been synthesized and characterized by some physico-chemical studies; elemental, spectral (IR, UV, NMR, Mass), magnetic, and conductance analyses. The CHN elemental analysis data showed the formation of 1:1 [M:L] complexes. The obtained molar conductance values revealed non-electrolytic nature. The results of magnetic moment measurements supported diamagnetic phenomenon for the complexes. The infrared spectral data displayed the main coordination sites of ligands towards Pb2+ ions. The electronic spectral results of the complexes showed π→π* (phenyl ring), n→π* (HC=N), CT transition. Based on analytical data trigonal pyramidal geometry for the prepared complexes has been proposed. The antibacterial activity of the prepared complexes was also studied against some gram positive and gram negative bacteria. It is found that some of the complexes are quite effective against tested bacteria.
