摘　　要：A novel dicyanamido-bridged 3D polymeric complex {[Zn2（bpa）2（dca）]dca}n （1） （dca = dicyanamide anion,bpa = 1,2-bis（4-pyridyl）ethane） has been synthesized by reacting 1,2-bis（4-pyridyl）ethane with zinc salt in the presence of sodium dicyanamide,and characterized by elemental analysis,IR spectra and X-ray diffraction. It crystallizes in the monoclinic system,space group C2/c with a = 18.587（3）,b = 20.070（3）,c = 8.7957（13） ,β = 100.611（2）o,V = 3225.0（8） 3,Mr = 539.92,μ = 0.789 mm-1,F（000） = 1116,Z = 4,ρ = 1.112 （g/cm3）,R = 0.0582 and wR = 0.1762. Complex 1 forms a 3D porous framework through the bpa and dca ligands,and gives 1-D coordination channels encapsulated by the guest dca molecules. Complex 1 also displays strong photo-luminescent properties in the solid state at room temperature.A novel dicyanamido-bridged 3D polymeric complex {[Zn2（bpa）2（dca）]dca}n （1） （dca = dicyanamide anion,bpa = 1,2-bis（4-pyridyl）ethane） has been synthesized by reacting 1,2-bis（4-pyridyl）ethane with zinc salt in the presence of sodium dicyanamide,and characterized by elemental analysis,IR spectra and X-ray diffraction.
