A novel dicyanamido-bridged 3D polymeric complex {[Zn2(bpa)2(dca)]dca}n (1)(dea=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)(A),β= 100.611(2)°,V=3225.0(8)(A)3,Mr= 539.92,μ= 0.789 mm-1, F(000)=1116, Z=4,(p)=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.
