| 摘 要： | A new cobalt compound, {Co(H2btec)(2,2'-bipy)(H2O)3]·H2O}n (1, H4btec =1,2,4,5-benzenetetracarboxylic acid, 2,2'-bipy = 2,2'-bipyridine), has been synthesized and characterized by single-crystal X-ray diffraction, elemental analysis, IR and X-ray powder diffraction. The crystal belongs to the triclinic system, space group P-1, with a = 7.230(3), b = 11.626(5), c =14.001(6) (A), α = 108.12(0)°, β= 95.85(0)°, V= 1095.33(157)(A)3, C20H20CoN2O12, Mr= 539.31,Z=2, Dc = 1.635 g/cm3,μ = 0.855 mm-1, F(000) = 554, R = 0.0427 and wR = 0.1042 for 3883 observed reflections (Ⅰ ＞ 2σ(Ⅰ)). The title compound features a discrete molecular structure, which is connected with each other through extensive O-H…O hydrogen bonds into an intricate 3D supramolecular network. Additionally, two different patterns of π-π stacking interactions further consolidate the framework.
