在水中合成了两种新的有机-金属氧酸盐电荷转移配合物H3PMo12O40*4.5CO(NH2)2*2.5H2O和H3PMo12O40*12CO(NH2)2，用IR、UV、TG、XRD及元素分析对其进行了表征。结果表明两种化合物中均存在［(H2N)2COH］+，阴离子保持Keggin结构，但Keggin结构由于尿素的有机给体作用发生了不同程度的畸变。H3PMo12O40*4.5CO(NH2)2*2.5H2O在固态，H3PMo12O40*12CO(NH2)2的水溶液具有光致变色效应。

Two new organo-polyoxometalate charge-transfer complexes H3PMo12O40*4.5CO(NH2)2*2.5H2O and H3PMo12O40*12CO(NH2)2 were synthesized and their structures were elucidated by IR,UV,TG,XRD and elementary analyses. 　　The results indicated that there is charge transfer between urea and polyanion and the existence of ［(H2N)2COH］+.Both of the complexes keep the Keggin structure of anion,but the Keggin structure is more or less transformed under the influence of urea.H3PMo12O40*4.5CO(NH2)2*2.5H2O showed photochromism in its solid state,while H3PMo12O40*12CO(NH2)2 showed photochromism in its water solution.
