合成了配合物双(4-氨基苯甲酸)(1,10-邻菲罗啉)锌(Ⅱ),通过元素分析、红外光谱对其进行了表征。用X-射线单晶衍射测定了该化合物的晶体结构。化合物晶体属单斜晶系,空间群C2/c,晶胞参数为:a=4.353 9(1)nm,b=1.179 3(2)nm,c=3.079 1(1)nm,β=134.952(1)°,V=11.189(2)nm3,Z=16,F(000)=5 056,Dc=1.444 g/cm3,μ=0.936 mm-1,S=1.000,R1=0.067 2,wR2=0.177 6。配合物通过1,10-邻菲罗啉中的两个氮原子和对氨基苯甲酸根中的两个氧原子配位,形成六配位不规则八面体结构。

[ Zn （O2CC6H4NH2-p）2（1,10-phen） ]·5H2O was synthesized and characterized by elemental analysis and IR. The crystal structure was determined by X-ray single crystal diffraction. The crystal is of monoclinic form with a space group of C2/c. The unit cell parameters are： α =4. 353 9（ 1 ） nm, b=1.179 3（2） nm, c=3.079 1（1） nm, β =134.952（1）°, V=11.189（2） nm^3, Z=16, F（000） =5056, Dc =1.444g/cm^3, μ=0.936mm^-1, S=1.000, R1=0.0672, and ωR2 = 0.177 6.Through the complexation of the two N atoms of 1 , 10-phenanthroline with the two O atoms of 4-amino-benzoic acid, a complex of octahedral structure with six irregular coordinations of Zn atom was formed.
