One-dimensional infinite chain organotin complexes: Synthesis and structural characterization of triphenyltin(IV) thiophen-2-carboxylate and triphenyltin(IV) 4-pyridinylcarboxylate

Abstract

Triphenyltin(IV) thiophen-2-carboxylate (<b>1</b>) and triphenyltin(IV) 4-pyridinylcarboxylate (<b>2</b>) have been synthesized by the reaction of sodium 2-thiophenylcarboxylate and sodium 4-pyrid inylcarboxylate with the triphenyltin(IV) chloride and characterized by IR,¹H NMR, MS and single crystal X-ray diffraction. In the crystals of <b>1</b>, the tin atoms are rendered four coordinated in a distorted tetrahedral structure. Due to the presence of a close intermolecular Sn^...S interaction of 3.339Å, the structure can be described as a weakly-bridged one-dimensional chain polymer. In the crystals of <b>2</b>, the tin atom is five coordinated with bridging pyridine N atom and resulting structure is one-dimensional chain polymer.
