A Zn-based coordination polymer [Zn(2-cb)2(4,4’-bpy)0.5]n (1, 2-cb = 2-chloro- benzoate, 4,4’-bpy = 4,4’-bipyridine) was prepared by hydrothermal synthesis using 2-chloro-benzoic acid and 4,4’-bipyridyl as ligands. The compound was characterized by elemental analysis, IR, TGA, and X-ray single-crystal diffraction. The crystal belongs to the monoclinic system, space group P with a = 8.0471(5), b = 9.7338(6), c = 11.7830(7), α = 96.2230(10), β = 92.542(2), γ = 103.7560(10)°, V = 888.84(9)3, Z = 2, Mr = 454.57, Dc = 1.698 g/cm3, μ(MoKα) = 1.708 mm-1, F(000) = 458, the final R = 0.0359 and wR = 0.0936 for 3167 observed reflections with I > 2σ(I). The crystal analysis indicates that 1 exhibits a 1-D chain structure constructed by 4,4’-bpy and a dicaryon secondary-building-unit of [Zn2(2-cb)4]. Luminescence analysis revealed that compound 1 emits blue fluorescence with a fluorescence lifetime of 55.03 ns.
