Abstract

A dinuclear anionic complex, Bu4N[Me2SnCl(S)ClSnMe2Br], has been synthesized in chloroform solution by reacting (Me2SnS)3, Me2SnCl2, and Bu4NBr. Attempts to isolate the anionic complex using tetramethylammonium cation were unsuccessful. The anion possesses two five-coordinate tin(IV) units bridged by sulfide and bromide. X-ray diffraction study revealed the possibility of a weak Sn–Sn bond in the complex. Theoretical (DFT) studies have been carried out to analyze the nature of metal–metal interaction in the complex.
