New mono-, di- and tri-organotin(W) derivatives containing the neutral bis(2-pyridylthio)methane ligand, [(pyS)(2)CH2] and tris(2-pyr-idylthio)methane ligand, [(pyS)(3)CH] have been synthesized from reaction with SnRnCl4-n (R = Me, Bu-n, Ph and Cy, n = 1-3) acceptors. Mono-nuclear adducts of the type {[(pyS)(2)CH2]RnSnCl4-n} and {[(pyS)(3)CH]RnSnCl4-n} have been obtained and characterized by elemental analyses, FT-IR, ESI-MS, multinuclear (H-1 and Sn-119) NMR spectral data. The H-1 and Sn-119 NMR and ESI-MS data suggest for the triorganotin(IV) derivatives a complete dissociation of the compounds in solution. The mono- and di-organotin(IV) derivatives show a greater stability in solution, and their spectroscopic data are in accordance with the existence of six-coordinated RSnCl3N2 or R2SnCl2N2 species.

Abstract:	New mono-, di- and tri-organotin(W) derivatives containing the neutral bis(2-pyridylthio)methane ligand, [(pyS)(2)CH2] and tris(2-pyr-idylthio)methane ligand, [(pyS)(3)CH] have been synthesized from reaction with SnRnCl4-n (R = Me, Bu-n, Ph and Cy, n = 1-3) acceptors. Mono-nuclear adducts of the type {[(pyS)(2)CH2]RnSnCl4-n} and {[(pyS)(3)CH]RnSnCl4-n} have been obtained and characterized by elemental analyses, FT-IR, ESI-MS, multinuclear (H-1 and Sn-119) NMR spectral data. The H-1 and Sn-119 NMR and ESI-MS data suggest for the triorganotin(IV) derivatives a complete dissociation of the compounds in solution. The mono- and di-organotin(IV) derivatives show a greater stability in solution, and their spectroscopic data are in accordance with the existence of six-coordinated RSnCl3N2 or R2SnCl2N2 species.
