摘要
用ＥＸＡＦＳ，ＦＴＩＲ以及ＩＣＰ等实验方法，对脱氧胆酸钇的结构进行了初步探讨。实验结果证实，钇与脱氧胆酸配位，生成稀土络合物，其中钇周围有八个氧原子，配位数为八．Ｙ—Ｏ平均距离为０．２３４ｎｍ。脱氧胆酸中羧基氧原子、羟基氧原子均与钇发生配位作用。
Coordination structure of yttrium deoxycholate complex has been studied by EXAFS, FTIR and ICP methods. It was observed that yttrium coordinated with deoxycholic acid, and rare earth complex formed. In this complex, there are eight oxygen atoms surrounding each yttrium atom, and the average bond distance between yttrium atom and oxygen atom is 0. 234nm. The oxygen atoms that coordinated with yttrium were offered by both carboxyl and hydroxyl groups of deoxycholic acid.
