摘　　要：以三氧化二锑和巯基乙酸在水溶液中反应合成了配合物HSb(SCH2COO)2,并通过元素分析、红外光谱、X射线物末衍射进行了表征,利用单晶X射线四圆衍射法测定了晶体结构.结果表明该配合物晶体属于单斜晶系,C2/c空间群.晶胞参数为:a=1.40005(8)m.b=1 19121(8)nm,c=1.23588(8)nm,β=126.822(1).,V=1.6499(2)nm3,D=2.439 g@cm3,Z=8,R1=0.0250.并对X射线粉末衍射数据进行了指标化。The solid complex of HSb (SCH2COO)(2) was synthesized through a reaction between antimony trioxide and thioglycollic acid in the aqueous solution. The complex was characterized with elemental analyses, infrared spectra, X - ray powder diffraction and X - ray crystal structure. The crystal structure of the complex belongs to monoclinic system, space group C2/c, with lattice parameters: a = 1.40005(8) nm, b = 1.19121 (8) nm, c = 1.23588(8) nm, beta = 126.822(1), V = 1.6499(2) nm(3), D-c = 2.439 g(.)cm(-3), Z = 8 and R-1 = 0.0250. The antimony ion bonds directly to the sulfur atom of the thiohydroxy - group and the oxygen atom of the carboxyl - group. There is not only the hydrogen bond of intermolecule, but also the coordination bonds of the antimony ion - sulfur or - oxygen atom of intermolecule. The results of indexes to the X - ray powder diffraction data for the complex are consistent with the results of single crystal.
