铕与β-丙氨酸配合物的合成及晶体结构

Synthesis and crystal structure of europium complex with β-alanine

The complex,｛[Eu2（β-ala）6（H2O）4]（ClO4）6.H2O｝n,was synthesized in an aqueous solution with a pH value of 3.5. Its crystal structure was determined by X-ray diffraction method.The crystal was triclinic with space group of Pī.The cell parameters were a=0.9285（1）nm,b=1.2889（1）nm,c=2.1665（3）nm,a=76.94（1）。,β=81.05（1）。 ,γ=83.05（1）。,V=2.4850（6）nm3,Z=2,Dc=2.038Mg.m-3.The structure of the complex could be viewed as an one-dimensiomal infinite chain. The europium ion was nine-coordinated with a geometry of distorted mono capped square
