Synthesis and Crystal Structure of a Novel Mercapto-organotin Complex: Et_3NH Ph_2SnCl(μ~2-SCH_2COO^-)

摘要

A novel complex [Et3NH] [Ph2SnCl(μ2- SCH2COO-)] has been unexpectedly obtained by the reaction of Ph3SnCl and HSCH2COOH in 2:1 molar ratio in the presence of organic base Et3N. Possible dephenylation mechanism was illustrated. The X-ray diffraction study has shown that the title complex consists of cation moiety [Et3NH] and anion moiety [Ph2SnCl(μ2 - SCH2COO)] with tin(IV) in a trigonal bipyramidal coordination geometry.
