Abstract

The new sodium bis(2-pyridylthio)acetate ligand, Na[(pyS)(2)CHCO2], has been prepared in ethanol solution using 2-mercaptopyridine, dibromoacetic acid and NaOH. New tri-organotin(IV) derivatives containing the anionic bis(2-pyridylthio)acetate have been synthesized from reaction between SnR3Cl (R = Me, Bu-n, Ph and Cy) acceptors and Na[(pyS)(2)CHCO2]. Complexes of the type {[(pyS)(2)CHCO2]SnR3} have been obtained and characterized by elemental analyses, FT-IR, ESI-MS, multinuclear (H-1 and Sn-119) NMR spectral data and X-ray crystallography. Crystallisation of the compound {[(pyS)(2)CHCO2]Sn(CH3)(3)}(n), from chloroform/ diethyl ether solution, yielded the complex {[(pyS)(2)CHCO2]Sn(CH3)(3)}(n)center dot CHCl3, which has been characterized by X-ray crystallography.
