| Abstract: | The crystal structure of gadolinium L-proline (Pro) complex Gd2-(C5H9NO2)6 (H2O)6] (ClO4)6 has been determined. The complex crystallizes in the triclinic space group PI with following crystal data: a = 9. 906(3), b=13. 052(5), c = 13.703(5) A. α=109. 63(3), β=110.31(2), γ=100. 73(3)°, V=1470.3(9) A3.Mr=1710. 1, F(000) = 854,μ=26. 30 cm-1, Dc = 1. 931 g/cm3, Z=1.The structure was refined to the final R of 0. 048 for 3804 reflections. The structure is of one-dimensional chain, in which each gadolinium ion lies at the center of a distorted square antiprism of the eight oxygen atoms provided by four bridging carboxylate groups from four Pro ligands, a terminal carboxylate group from one terminal Pro ligand and three water molecules and the two neighbouring gadolinium ions are linked to each other through the two bridging carboxylate groups from the two Pro ligands. The prolines exist in the form of H2 CCH2CH2(+NH2)CHCOO-, and the complexions in the crystal are linked together by the net of hydrogen bonds between theClO4- , NH2+ and the coordinated water molecules. |
