A series of organotin(IV) complexes with Schiff base ligand pyruvic acid 3-hydroxy-2-naphthoyl hydrazone [R2SnLY]2, L = 3-HO–C10H6-2-CONHNC(CH3)COOH, R = n-C4H9, Y = CH3OH (1), R = n-C4H9, Y = N (2), R = PhCH2 (3), R = Ph, Y = CH3OH (4), R = Me, (5) and [R3SnLY], L = 3-HO–C10H6-2-CONHNC(CH3)COOH, R = n-C4H9, Y = H2O, (6), R = Ph (7), R = Me (8) have been synthesized. These complexes have been characterized by elemental analysis, IR, 1H and 119Sn NMR spectra. The crystal and molecular structure of complexes 1, 2 and 6 have been determined by X-ray single crystal diffraction. Results showed that complex 1 has a dimeric structure and the central tin atom is rendered seven-coordinate in a distorted pentagonal-bipyramid configuration. The complex 2 has a monoclinic structure and the central tin atom is rendered six-coordinate in octahedrally configuration with a planar of SnO3N unit and two apical aryl C atoms. And the whole structure consists of molecular units connected by weak intermolecular Sn⋯N and O–H⋯N interactions. In the complex 6, the central tin atom is five-coordinate in distorted trigonal-bipyramidal geometry.
