摘要
合成了钇与亚胺基二乙酸的配合物，用X射线衍射法测定了配合物的单晶结构，化学式为［Y｛H2N（CH2COO）2｝（H2O）4］（ClO4）2·1．25H2O．晶体属三斜晶系，P1空间群．晶胞参数：a=0．9254（1）nm，b=0．9922（1）nm，c=1．0658（2）nm，α=71．481（10）°，β=77．950（10）°，γ=65．350（10）°，V=0．8401（2）nm3，Z=2，Dc=2．034g／cm3．Y3+离子的配位数为8，其配位多面体为三角十二面体．
The title complex was synthesized and its crystal structure was determined by sin-gle crystal X-ray diffraction technique with a four circle diffractometer to give final R1 value 0.0509 and WR2 value 0.1337. The crystal is triclinic with space group P 1. The unit cell parameters are: a=0.9254 (1)nm, b=0.9922(1) nm, c=1.0658(2)nm, α=71.481(10)°, β=77.950(10)°, γ=65.350(10)°, V=0.8401(2)nm3, Z=2, Dc=2.034g/cm3.The complex is a two-dimensional polymeric molecule.In addition, every yttrium atom is co-ordinated by four oxygen atoms from four iminodiacetic acid molecules and four oxygen atoms from water molecules.The coordination number of yttrium ion is 8 and the coordina-tion polyhedron is a distorted trigondodecahedron.
