摘　　要：本文合成了未见文献报道的二环己基-甲基锡氧化物及其二十个羧酸酯衍生物,经红外、核磁及X射线衍射分析确定了化合物的结构.结果表明,所合成的二环己基-甲基锡脂肪酸酯为分子间氧桥相连的五配位聚合结构,而取代苯甲酸酯则为单分子变形四面体结构.化合物的生物活性测定结果表明,这是一类具有高效杀螨、杀菌及除草活性的有机锡化合物.Twenty novel methyldicyclohexyltin carboxylates were prepared and their structures were characterized with IR, NMR and X-ray diffraction. The results show that the methyldicyclohexyltin fattycarboxylates are five coordinate, carboxylate-bridged polymers, while the aromatic carboxylates are four coordinate. The results of bioassay indicate that these compounds are of high acaricidal, fungicidal and herbicidal activitives.
