| Abstract: In this paper we describe the molecular and crystal structures of the K3[Y(NTA)2(H2O)]· 6H2O(H3NTA=nitrilotriacetic acid). The crystal data are as followsmonoclinic system, C2/c space group, a=1.5268(3)nm,b=1.2833(3)nm,c=2.6079(5)nm,β =96.03(3)°,V=5.0815(18)nm3,Z=8,M=708.68,Dc=1.852gcm-3,μ =2.875mm-1,F(000)=2880.The final R1 and wR2 are 0.0636 and 0.1523 for 4264 [I >2.0σ (I)] unique reflections and 0.1178 and 0.1651 for all 4364 reflections,respectively.In the title complex, the anion [Y(NTA)2(H2O)]3- has a nine-coordination structure with distorted monocapped square antiprism. Each group acts as a tetradentate ligand with three Oatoms and one Natom and a H2O molecule caps a quadrilateral face as a ligand.It can be known that the Y(Ⅲ) ion can form a high-coordinate compound with aminopolycarboxylic acid ligands because it has a larger ionic radius (0.104nm). |
