Abstract
Complexes of 2-(2′-pyridyl)quinoxaline (L) with R2SnCl2 (R=Me, Et, Bun) have been synthesized and characterized using IR, far-IR, 119Sn Mössbauer, 1H and 13C spectroscopies. The X-ray crystal structure of Et2SnCl2L shows a bidentate chelating behaviour of L, which is observed in all the diorganotin compounds presented. Interaction of the ligand L with SnCl4 resulted in the formation of a salt with the formula [(LH)2]2+[SnCl6]2−. Solution studies of the complexes R2SnCl2L (R=Me, Et, Bun) revealed partial dissociation of the ligand in chloroform.
