Abstract

Eight diorganotin(IV) complexes of salicylaldehyde isonicotinylhydrazone (H2SalN) R2Sn(SalN) R = t-Bu 1, Ph 2, PhCH23, o-ClC6H4CH24, p-ClC6H4CH25,m-ClC6H4CH26,o-FPhCH27, p-FC6H4CH28 were prepared. All complexes 1–8 have been characterized by elemental, IR, 1H, 13C and 119Sn NMR analyses. The crystal structures of H2SalN and complex 1 were determined by X-ray crystallography diffraction analyses. Studies show that H2SalN is a tridentate planar ligand. For complex 1, the tin atom lies in this plane and forms a five- and six-membered chelate ring with the tridentate ligand. A comparison of the IR spectra of the ligand with those of the corresponding complexes, reveals that the disappearance of the bands assigned to carbonyl unambiguously confirms that the ligand coordinate with the tin in the enol form.
