双邻苯二酚锑二乙基羟乙铵的晶体结构

摘要/Abstract

摘要： 双邻苯二酚锑二乙基羟二铵晶体的分子式是C₁₈H₂₄O₅NSb,属正交晶系,空间群为P_2₁2₁2₁,其晶胞参数a=9.069Å,b=11.636Å,c=17.786Å,每单胞中有四个分子。收集到的独立衍射点共有2268个,用大于2σ的2106个衍射点进行Patterson函数合成,解出粗结构。结构经全矩阵最小二乘修正,最终偏离因子R=0.0326,R_w=0.041。结构表明锑原子与两个邻苯二酚上的氧配合,为准三角双锥构型。

Abstract: The crystal of diethylthanolammonium bis (o-diphenol) antimonate (Ⅲ)belongs to orthorhombic space group P₂₁₂₁₂₁ with unit cell constants:a=9.096Å, b=11.636Å, c=17.786Å and Z=4. The coordinates of Sb atoms were derived from three-dimensional Patterson function and the locations of non-hydrogen atoms from succesive Fourier and difference Fourier syntheses.The structure was refined to R=0.0326, R_w=0.041 for 2106 independent reflections. It was considered that Sb atom makes use of four sp³d hybrid orbitals to conbine with four O Atoms in formation of a pesudo-trigonal bipyramidal configuration.
