Synthesis,Characterization and Properties of Bis{oxo—bis[heteroaromatic carboxylatodibenzyltin（Ⅳ）]}and Crystal Structure of Bis{oxo—bis[2—furylcarboxylatodibenzyltin（Ⅳ）]}

IntroductionThe organotin( ) derivatives of carboxylicacids have been extensively studied due to their bio-logical activities[1— 4] . In recent years more andmore reports on the synthesis,antitumour activi-ties,biocidal activities,antibiotic activities andstructural elucidation of various organotin ( )derivatives of carboxylic acids have appeared[5— 10 ] .In particular,the diorganotin ( ) complexes ofcarboxylic acids have aroused a considerable inter-est of some scientists in the structur…
