摘　　要：Two new Cu（II） coordination polymers, [Cu（FDA）（BPY）（H20）]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） A, β = 99.05（3）°, V= 1525.1（6） A3, Dc = 1.706 g/crn3, C16HI2CuN206, Mr = 391.82, F（000） = 796, μ（MoKa） = 1.470 mm-l, Z = 4, R = 0.0633 and wR = 0.1059 for 2389 observed reflections （1 〉 2a（I））, R = 0.0738, and wR = 0.1098 for all data. Complex 2 belongs to triclinic space group PI with a = 8.8660（18）, b = 8.9112（18）, c = 12.525（3） A, a = 88.41（3）, β = 69.38（3）, γ = 66.95（3）°, V = 845.2（3） A3, Dc = 1.681 g/cm3, CI6HI6CuN2Os, 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.Two new Cu（II） coordination polymers, [Cu（FDA）（BPY）（H20）]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.
