摘要
A new aromatic carboxylate ligand,namely 5-（pyrrolidin-1-yl）-1,3-benzenedicar-boxylic acid（H2pybdc）,was synthesized and characterized by FT-IR and single-crystal X-ray diffraction analysis.It crystallizes in triclinic system,P1 space group with a = 10.05（5） ,b = 11.53（5）,c = 12.92（6） ,α = 112.11（6）°,β = 92.79（7）°,γ = 102.98（7）°,V = 1337.113,Z = 4,Mr = 253.25,Dc = 1.258 g.cm-3,μ = 0.099 mm-1,F（000） = 536,the final R = 0.0822 and wR = 0.2575 for 1893 observed reflections（I 2σ（I））.Based on it,a two-dimensional grid-type Zn（Ⅱ） coordina-tion polymer of {[Zn（pybdc）（bpy）（H2O）].2H2O.0.5CH3OH}n（1） was solvothermally synthesized,which crystallizes in triclinic,space group P1 with a = 10.218（5） ？,b = 11.176（5） ,c =11.350（5） ,α = 95.855（5）°,β = 94.248（5）°,γ = 101.421（5）°,V = 1257.9（2） 3,Z = 2,Mr = 524.84,Dc = 1.386 g.cm-3,μ = 1.024 mm-1,F（000） = 546,the final R = 0.0635 and wR = 0.1879 for 3913 observed reflections（I 2σ（I））.
