摘要： 利用酯基锡与缺位Keggin结构杂多阴离子PW9O349-反应,合成了6种新的杂多阴离子--有机金属配合物M9[(R'OOCCHR"CH2SnOH2)3(PW9O34)2]·xH2O(M=(CH3)4N+,K+;R'=CH3_,CH3CH2_;R"=H,CH3_),通过元素分析、IR光谱、紫外电子光谱、1HNMR、31PNMP、183WNMR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,确定该系列配合物为A-β-PW9型夹心配合物结构.

Abstract: Six new heteropoly anion-organometallic complexes M9 (R'OOCCHR″CH2SnOH2)3·(PW9O34 )2]· x H2O(M=(CH3)4N+, K+; R'=CH3 _, CH3CH2 _; R″=H, CH3_ ) have been synthesized by reaction of estertin with Na8HPW9O34. The products were characterized and their properties were studied by elemental analysis, IR, UV, 1HNMR, 31 P NMR, 183W NMRand TGA-DSCmeasurements. The sandwich structure of A, β-PW9 type for these complexes were determined.

Key words: Heteropoly anion, Estertin, Complexes, Syntheses, Sandwich structure
