Abstract: A novel microporous coordination polymer [Co2(Hisor)2(4,4′-bpy)2(H2O)2]·4,4′-bpy was synthesized by hydrothermal reaction and characterized by single crystal X-ray diffraction, elemental analysis and IR spectrum. The crystal belongs to the monoclinic system and space group is P2/n with a=1.040 6(3) nm, b=1.138 8(4) nm, c=1.854 7(6) nm, β=102.991(6)°, V= 2.141 6(12) nm3, Z=2, Dc=1.443 Mg/m3, Mr=930.62, μ=0.842 mm-1, F(000)=952, GOF= 1.072, R=0.065 4, wR=0.146 8[I>2σ(I)]. There are two crystallographically independent Co(Ⅱ) ions in the title complex. The Hisor2- and 4,4′-bpy link the metal ions into 2D grids with dimension of 0.522 3 nm×1.138 8 nm. There are O—H…O and N—H…O hydrogen bonds in the complex resulting in the formation of 3D network with 1D channels, in which are free 4,4′-bpy molecules.

Key words: Microporous coordination polymer, Crystal Structure, 5-Carboxyluracil
