摘要

Complexes of 2-(2'-pyridyl)quinoxaline (L) with R_2SnCl_2 (R = Me, Et, Bu~n) have been synthesized and characterized using IR, far-IR, ~(119)Sn Mossbauer, ~1H and ~(13)C spectroscopies. The X-ray crystal structure of Et_2SnCl_2L shows a bidentate chelating behaviour of L, which is observed in all the diorganotin compounds presented. Interaction of the ligand L with SnCl_4 resulted in the formation of a salt with the formula [(LH)_2]~(2+)[SnCl_6]~(2-). Solution studies of the complexes R_2SnCl_2L (R = Me, Et, Bu~n) revealed partial dissociation of the ligand in chloroform.
