摘　　要：A dinuclear Cd(Ⅱ) complex [Cd2(N3)2L2Cl2]2·H2O(1) [L=4'-(4-cyanophenyl)-2,2'∶6',2″-terpyridine] was synthesized by reaction of ligand L with CdCl2 and NaN3 using solvothermal method and its structure was determined by X-ray crystal structure analysis. The structure indicates that the complex crystallizes in monoclinic, space group C2/c with a=1.644 5(16) nm, b=1.441 9(12) nm, c=1.918 1(18) nm, β=100.349(11)°. V=4 474(7) nm3, Z=2, Dc=1.570 Mg·m-3, μ=1.120 mm-1, F(000)=2 100, and final R1=0.039 3, wR2=0.081 1. The result shows a Cd(Ⅱ) ion was six-coordinated by a tridentate 4'-(4-cyanophenyl)-2,2'∶6',2″-terpyridine ligand and one bridging nitrogen atom of the azide group in the basal position and an chloride atom and the other bridging nitrogen atom of the azide group in the axialone, to form a distorted octahedral-pyramidal geometry.

The result shows a Cd（II） ion was sixcoordinated by a tridentate 4＇ -（4-cyanophenyl）-2,2＇ ：6＇ ,2″-terpyridine ligand and one bridging nitrogen atom of the azide group in the basal position and an chloride atom and the other bridging nitrogen atom of the azide group in the axialone, to form a distorted octahedral-pyramidal geometry.
