R3SnCl (R = o-ClBz 10, p-ClBz 11, p-CNBz 12) with the Schiff-base ligand pyruvic acid salicylhydrazone in a 1:1 molar ratio. All complexes were characterized by elemental analysis and IR, 1H, and 119Sn NMR spectroscopy. The crystal structures of complexes 1, 2, 3, 7, and 10 have been determined by X-ray single crystal diffraction analyses, which show that the tin atoms of 1, 2, 3, and 10 are all seven-coordinate
