组氨酸的Keggin结构杂多金属氧酸盐的合成及性质研究

Study on synthesis and properties of histidine heteropolyoxometalates with Keegin structure

首次合成了组氨酸的Ｋｅｇｇｉｎ 结构（ＸＭ１２Ｏ４０ｎ－ ，Ｘ＝ Ｐ，Ｓｉ，Ｍ＝ Ｗ，Ｍｏ）３ 种杂多金属氧酸盐化合物用元素分析、ＩＲ、ＵＶ、ＴＧ－ ＤＴＡ 等方法对标题化合物进行了表征．结果表明该类化合物仍保持Ｋｅｇｇｉｎ 结构。

It was first reported that three compounds of histidine heteropolyoxometalates with the Keggin structure (XM 12 O 40 n - ,X=P,Si,M=W,Mo) had been synthesized. They were characterized by means of elementary analysis, IR, UV, TG-DTA.It was known that XMO 40 n - anions with a Keggin structure was kept unchanged and the anion and histidine were combined by means of electrostafic forces.
