摘要
Solvothermal reaction of 2,5-furandicarboxylic acid （H2FDA） ligand and Ca（NO3）24H2O affords a new coordination polymer, [Ca2（FDA）2（DMAC）（H2O）]n （1）. The structure has been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses, IR, powder X-ray diffraction and TGA. Compound I crystallizes in triclinic, space group Pi with a = 9.5387（19）, b = 10.425（2）, c = 11.590（2）A, a = 75.02（3）, fl = 84.80（3）, y = 80.99（3）~, V = 1098.1（4） A3, Dc = 1.492 g/cm^3, C16H15Ca2NO12, Mr = 493.45, F（O00） = 508, p（MoKa）= 0.580 mm-1, Z= 2, R = 0.0436 and wR = 0.0944 for 3865 observed reflections （I〉 2σ（/））, and R --- 0.0595 and wR = 0.1015 for all data. The structure of 1 exhibits a three-dimensional network with layer-pillar structure.
