Hydrothermal Synthesis, Crystal Structure and Photoluminescent Property of a Metal-organic Coordination Polymer with Supramolecular Structure: [Cd_2(dpphen)_2(BDC)_(0.5)Cl_3]_n

摘要

A novel metal-organic coordination polymer [Cd_2(dpphen)_2(BDC)_(0.5)Cl_3]_n (dpphen = 4,7-diphenyl-1,10-phenanthroline, BDC = terephthalate) 1 has been obtained by using hydrothermal synthesis and characterized by elemental analysis, IR, fluorescence spectrum and single-crystal X-ray diffraction. The complex crystallizes in triclinic, space group P1 with a = 9.981(5), b = 10.436(5), c = 21.104(10) k, α = 94.640(7), β = 103.160(7), γ = 92.958(8)°, V = 2127.8(17) A~3, C_(52)H_(34)Cd_2Cl_3N_4O_2, M_r = 1077.98, D_c = 1.682 g/cm~3, μ(MoKα) = 1.237 mm~(-1), F(000) = 1074, Z = 2, the final R = 0.0314 and wR = 0.0757 for 7358 observed reflections (I > 2σ(I)). Furthermore, compound 1 shows blue photoluminescent property at room temperature.
