摘　　要：The two title complexes,[Cd2(phen)2(succ)(H2O)2](NO3-)2 ·3H2O(1)and [Cd2(phen)2(glut)2][Cd2(phen)2(Cl-)2] 2NO3-·14H2O(2)(succ =succinic acid,glut =glutaric acid,phen=1,10-phenanthroline)have been synthesized at room temperature,and characterized by elemental analysis,IR spectrum and X-ray crystal diffraction.The results show that the complex 1 belongs to monoclinic system with space group P2(1)/c and cell parameter: a=15.373(5),b=13.786(4),c=25.434(7),β=104.582(6)°,V=5217(3)3,Z=4,,Dc=1.624g/cm3,μ(MoKα)=0.895mm-1,F(000)=2576,R1=0.0699,wR2=0.1280.And complex 2 belongs to triclinic system,space group Pī,cell parameter: a=14.131(4),b=14.546(4),c=15.392(5),β=93.731(6),V=2674.93,Z=2,Dc=1.613 g/cm3,μ(MoKα)=0.921 mm-1,F(000)=1316,R1=0.0746,wR2=0.121.Complex 2 has two independent structure and Cd(Ⅱ) is rare seven-coordinated mode.The two complexes formed 2D molecular architectures by hydrogen-bonding and π-π stacking interactions.The two title complexes, [ Cd2 （phen） 2 （succ） （ H2O） 2 ] （ NO3^- ） 2 · 3 H2O （ 1 ） and [ Cd2 （ phen ） 2 （glut） 2 ] [ Cd2 （ phen ） 2 （ Cl^- ） 2 ] 2NO3^- · 14H2O （2） （succ = succinic acid, glut = glutarie acid, phen = 1,10-phenanthroline） have been synthesized at room temperature, and characterized by elemental analysis, IR spectrum and X-ray crystal diffraction. The results show that the complex I belongs to monoclinic system with space group P2（ 1 ）/c and cell parameter： a = 15. 373（5） ,b = 13. 786（4） ,c =25. 434（7 ） A,β = 104. 582（6 ） °, V = 5217（ 3 ）A^3 ,Z = 4, ,Dc = 1. 624g/cm^3 μx（MoKα） =0. 895mm^-1 ,F（000） = 2576 ,R1 =0. 0699, ωR2 =0. 1280.
