摘　　要：　利用酯基锡与缺位Keggin结构阴离子SiW9O10-34反应,合成了6种新的杂多阴离子有机金属配合物M4H3[(R′OOCCHR″CH2Sn)3(SiW9O37)]·xH2O(M=K+,(CH3)4N+;R′=CH3,CH3CH2;R″=H,CH3;x=6～12).通过元素分析、IR光谱、1HNMR、紫外电子光谱、循环伏安和TGA-DSC热分析等测试手段对标题配合物进行了表征和性质研究,确定该系列化合物为α-Keggin型三取代酯基锡杂多配合物.Six new organometallic heteropoly anion complexes M_4H_3[(R′OOCCHR″CH_2Sn)_3(SiW_9O_(37))]·xH_2O(M=K^+,(CH_3)_4N^+;R′=CH_3,CH_3CH_2;R″=H,CH_3;x=6～12)have been synthesized by the reaction of estertin with Na_(10)SiW_9O_(34)·xH_2O.The products were characterized and their properties were studied by elemental analysis,IR,~1H NMR,UV-Vis,electrochemical and TGA-DSC measurements.The results confirmed that they may posses similar structure to that reported in the known compound [(PhSn)_3(SiW_9O_(37))]^(7-).
