三(1-苯基-3-甲基-4-苯甲酰基-吡唑酮-5)二水合镱(Ⅲ)的晶体结构

SYNTHESIS AND STRUCTURE OF YTTERBIUM 1-PHENYL-3-METHYL-4-BENZOYL-5-PYRAZOLONATEDIHYDRATE

本文合成了Yb(PMBP)_3(H_2O)_2,并用X-射线单晶衍射法测定了晶体和分子的结构.配合物的晶体为单斜晶系,空间群为P2_1/n,a=24.498(3)(?),b=14(?)35(3)(?),c=14.888(5)(?),β=101.14(2)(?),V=5285.1(?)~3;Z=4.三个PMBP及两个水分子提供八个氧与镱配位形成四方反棱柱配位多面体.

In this paper, the title coordination compound was synthesized, the crystal and molecular structure have been determined by single crystal X-ray diffraction analysis. The crystal is monoclinic with space group P21/n. The unit cell parameters arc: a = 24.498(3)A, b=14.735(3)A, c=14.888(5)A, β= 101.14(2)° , V=5285A3, Z = 4. Each Ytterbium ion is surrounded by eight oxygen atoms, contributed by three PMBP and two water molecules, arranged at the vertexes of a square antiprism.
