Two new Cu(Ⅱ) coordination polymers,[Cu(FDA)(BPY)(H2O)]n(1) and {[Cu(FDA)(BPY)(H2O)]·2H2O}n(2)(H2FDA = 2,5-furandicarboxylic acid,BPY = 2,2-bipyridine),have been synthesized and structurally characterized by single-crystal X-ray diffraction as well as elemental analysis and IR.Compound 1 crystallizes in monoclinic,space group P21/c,with a = 7.5915(15),b = 8.4050(17),c = 24.204(6) ,β = 99.05(3)°,V = 1525.1(6) 3,Dc = 1.706 g/cm3,C16H12CuN2O6,Mr = 391.82,F(000) = 796,μ(MoKα) = 1.470 mm–1,Z = 4,R = 0.0633 and wR = 0.1059 for 2389 observed reflections(I > 2σ(I)),R = 0.0738,and wR = 0.1098 for all data.Complex 2 belongs to triclinic space group P1 with a = 8.8660(18),b = 8.9112(18),c = 12.525(3) ,α = 88.41(3),β = 69.38(3),γ = 66.95(3)°,V = 845.2(3) 3,Dc = 1.681 g/cm3,C16H16CuN2O8,Mr = 427.85,F(000) = 438,μ(MoKα) = 1.342 mm–1,Z = 2,R = 0.0290 and wR = 0.0690 for 2767 observed reflections(I > 2σ(I)),R = 0.0329 and wR = 0.0706 for all data.Complexes 1 and 2 are both coordination polymers with one-dimensional chain structures bridged by the protonated FDA ligands,which are assembled into three-dimensional supramolecular structures through hydrogen bonding interactions and π-π packing interactions between the chains.
