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.
