羧酸氧钒（Ⅳ）配合物的合成及表征

Synthesis and Characterization of Oxovanadium(Ⅳ) Carboxylate Coordination Compounds

合成了三水乳酸氧钒（Ⅳ）、二水苹果酸氧钒（Ⅳ）、己二酸氧钒（Ⅳ）和二苹果酸氧钒（Ⅳ）铵４种羧酸氧钒（Ⅳ）配合物，应用元素分析、热分析和红外光谱分析对它们的结构进行表征．

VO[(CH 3CH(OH)CO 2) 2(H 2O) 2]·H 2O, VO[CO 2CH(OH)CH 2CO 2(H 2O) 2],VO(CO 2(CH 2) 4CO 2)and (NH 4) 2[VO(CO 2CH(OH)CH 2CO 2) 2] were synthesized and characterized by elemental analyses, DTA, TG and IR. Their infrared frequencies were discussed and assinged applying group theory. Thermal decomposition processes of the compounds were also discussed according to assigned infrared frequencies of certain bonds of the compounds.
