| Abstract: | 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. |
