Synthesis and spectroscopic characterization of new tin(II) complexes containing nitrogen and oxygen donor ligands

Vol. 51, No. 1

Some new tin(II) complexes have been synthesized by the reactions of tin(II) methoxide with nitrogen donor ligands. The ligands used in these studies are condensation products of heterocyclic aldehydes/ketones and sulpha drugs. Their structures have been confirmed on the basis of elemental analyses, ultraviolet, infrared and multinuclear magnetic resonance (1H, (13)C and (119)Sn) spectral studies. The bivalent nature and their square pyramidal geometry around tin(II) have been deduced on the basis of 119Sn Mossbauer spectral data. Monomeric and non-electrolytic nature of these complexes have been confirmed by molecular weight determinations and conductance measurements.
