新型电荷转移多金属氧酸盐的合成和红外光谱研究

Syntheses and IR Spectra of New Charge Transfer Polyoxometalates

以４种道森结构的杂多酸和３种芳香杂环化合物为原料合成了１１种新型电荷转移多金属氧酸盐，研究了它们的红外光谱。结果表明：杂多酸形成电荷转移盐后，杂多阴离子的结构略有畸变但仍保持道森结构；有机给体和杂多阴离子之间存在电荷转移相互作用。

Eleven new charge transfer polyoxometalates have been synthesized from four heteropoly acids with Dawson structure and three heteroaromatic compounds.IR spectra studies indicate that the Dawson structure of the heteropolyanion has a little change after a charge transfer polyoxometalate was formed,and that charge transfer interaction is present between organic donor and heteropolyanion.
