摘　　要：采用水热法合成了一个分子式为[Co(eoba)(phen)(H2O)2]?H2O的配合物(H2boba = 4,4’-(乙烷-1,2-二氧基)-二苯甲酸,phen = 1,10-邻菲咯啉),并对其进行了元素分析、红外光谱、热重和X-射线单晶衍射的结构解析。该配合物(C28H26CoN2O9)属于单斜晶系,P2(1)/c空间群,晶体学数据:a = 13.708(5) &#197,b = 20.237(5) Å,c =10.158(5) Å,β = 105.071(5)?,V = 2721.0(18) Å3,Mr = 593.44,Dc = 1.449 g/cm3,μ(MoKα) = 0.688 mm-1,F(000) = 1228,Z = 4。直接法解析原子位置的结果显示:R = 0.0409,wR = 0.0933。该配合物为二维网状结构,并通过氢键和π–π堆积形成超分子结构。A coordination polymer formulated as [Co(eoba)(phen)(H2O)2]?H2O (H2boba = 4,4?-(ethane- 1,2-diyldioxy) dibenzoic acid, phen = 1,10-phenanthroline) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction. The title compound (C28H26CoN2O9) crystallizes in the monoclinic system, space group P2(1)/c with a = 13.708(5) Å, b = 20.237(5) Å, c = 10.158(5) Å, β = 105.071(5)?, V = 2721.0(18) Å3, Mr = 593.44, Dc= 1.449 g/cm3, μ(MoKα) = 0.688 mm-1, F(000) = 1228, Z = 4, the final R = 0.0409 and wR = 0.0933. It exhibits a two-dimensional network structure and extended into a supramolecular framework through hydrogen bonds and π-π interactions.
