摘要: 合成了化合物［Zn(IBG)(H2O)3］·2H2O (H2IBG = 1,3-苯二甲酰二甘氨酸),并通过X射线衍射对其单晶结构进行了测定.该结构属于正交晶系,空间群C222(1),分子量Mr=431.65,晶胞参数a=0.693 01(14) nm, b=0.772 56(14) nm, c=23.006 4(6) nm, V=1.609 61 nm^-3，Z=4, Dc=1.781 g·cm^-3, F(000)=888.0. 由于分子内和分子间氢键,使得分子结构更趋稳定.通过红外光谱(IR)、热重分析及XRD对化合物进行了表征.Abstract: The complex ［Zn(IBG)(H2O)3］·2H2O (H2IBG= isophthaloylbisglycine) was synthesized and its crystal structure was characterized by X-ray diffraction. The compound crystallizes in orthorhombic crystal system, space group C222(1), with Mr=431.65，a=0.693 01(14) nm，b=0.772 56(14) nm，c=23.006 4(6) nm, V=1.609 61 nm^-3，Z=4，Dc=1.781 g·cm^-3，F(000)=888.0. The molecular structures are stabilized by hydrogen bonds. The title compound was measured by IR, thermogravimetric analysis and XRD.
