Synthesis and Characterization of Tin (II) and Lead (II) Complexes with Benzylidene Aniline Ligand

The Schiff base (Benzylideneaniline molecule) and its complexes with Sn (II) and Pb (II) have been synthesized and characterized by various spectroscopic and electro-analytical techniques. The ligand, Benzylideneaniline has been synthesized by condensation reaction of benzaldehyde and aniline.The metal complexes were prepared by mixing of saturated solutions of metal salts and ligand in 1:2 ratios in methanol and Dimethylsulfoxide solvents, followed by their characterization using magnetic susceptibility, molar conductivity, chloride estimation and spectral studies. It was found that titled organic ligand acts as monodentate and in both complexes it is proposed to be interacted in metal to ligand 1: 2 ratio with the metals to form organotin(II) and organolead (II) complexes through the direct method. Overall experimental results show that a diamagnetic and square planar geometry of both complexes formed.
