摘　　要：标题配合物由高氯酸锌、1,10-二氮杂菲(phen)和苦味酸(HPA)反应而得。其晶体结构通过单晶X-射线衍射法测定,其晶体属三斜晶系,P 空间群,a = 11.311(2),b = 12.638(4),c = 13.713(4) , = 93.24(3), = 100.32(2) , = 106.50(2) , Z = 2, V = 1837.1(9) 3, Dc = 1.660 g/cm3, (MoK) = 0.763 mm-1, F(000) = 936, R = 0.0512, wR = 0.1152。在配合物中, Zn2+离子被2个水分子的2个氧和2个二氮杂菲中的4个氮配位,形成六配位的畸变八面体。苦味酸根作为外界离子以库仑力和氢键与内界离子结合。The tilte compound has been obtained from the reaction system of Zn(ClO4)2?H2O, 1, 10-phenanthroline and picric acid (molar ratio 1 : 3 : 2) in CH3OH-H2O solvent and structurally characterized by X-ray diffraction analysis. The crystal is of triclinic with space group P . The unit cell parameters are as follows: a = 11.311(2),b = 12.638(4),c = 13.713(4) 牛?= 93.24(3), = 100.32(2) , = 106.50(2) , Z = 2,V = 1837.1(9) 3, Dc = 1.660 g/cm3, = 0.763 mm-1, F(000) = 936, R = 0.0512 and wR = 0.1152. In the complex, the Zn(Ⅱ) cation is octahedrally coordinated to two 1, 10-phenanthroline ligands and two water molecules in cis disposition. The zinc-containing cation and picrate anions are held together by hydrogen bond and electrostatic attraction.
