A new Zn(II) coordination polymer [Zn3(BTC)2(4,4’-bpy)(CO)2]n(1, H3 BTC =1,3,5-benzenetricarboxylic acid, 4,4’-bpy = 4,4’-bipyridine) has been prepared through urothermal reaction of zinc nitrate hexahydrate with 1,3,5-benzenetricarboxylic acid and 4,4’-bipyridine, and characterized by elemental analysis, IR spectroscopy, TGA and powder XRD, and its crystal structure was determined by single-crystal X-ray diffraction analysis. The title compound crystallizes in the monoclinic system, space group C2/c, with a = 10.262(3), b = 18.838(5), c =15.083(4) A, β = 99.203(4)o, V = 2878.3(14) A3, C30H14Zn3N2O14, Mr = 822.54, Z = 4, Dc = 1.898g/cm3, μ = 2.561 mm-1, F(000) = 1640, R = 0.0363 and w R = 0.0932 for 2828 observed reflections(I> 2σ(I)). X-ray analysis shows that the asymmetric unit of the title compound contains two crystallographically unique Zn(II) atoms which are connected by BTC3- ligands and 4,4’-bpy coligands to form a 3D framework with 1D channels. The solid luminescence of ligand and the title complex was also studied at room temperature.
