摘　　要：在不同的水解条件下，合成羧乙基锗倍半氧化物（Ｇｅ－１３２）和乙氧羰基乙基锗倍半氧化物。采用快原子轰击质谱（ＦＡＢＭＳ）技术分别对３种化合物进行分析，证明有机锗化合物是以聚合物的形式存在，分子结构通式为｛［ＧｅＣＨ２ＣＨ２ＣＯＯＨ］２Ｏ３｝ｎ，聚合系数ｎ分别为１、２和３。bis_Carboxy_ethyl germanium sesquioxide(Ge_132) and its derivative bis_ethoxycarbonyl_ethyl germanium sesquioxide were synthesized at various hydrolysis temperatures.Relative molecular mass of these compounds were determined by fast atom bombardment mass spectrometry(FABMS).The results showed that these organic germanium compounds were polymeric substances.The general molecular formula is {GeCH2CH2COOH]2O3}n,and the coefficient of polymerization n equals to 1,2,or 3.
