摘　　要：采用水热法合成了一种基于1,3-二[3,5-(二羧基)苯氧基]-2-羟基丙烷(H4L)和4,4′-联吡啶(Bipy)的Co(Ⅱ)配合物:[Co2(L)(Bipy)2]n(1),并利用红外光谱(IR)、紫外-可见光谱(UV-Vis)、热重分析(TGA)、单晶X-射线衍射、粉末X射线衍射(XRD)及元素分析对其结构进行了表征。配合物1属单斜晶系,C2/c空间群。在配合物1中,由2个六配位钴原子组成的双核原子簇可简化为八面体型6-连接点,连接4个羧酸配体分子L和其他2个双核原子簇。羧酸配体L可简化为四面体型4-连接点,连接4个双核原子簇。平行排列的2个联吡啶分子连接两个相邻双核原子簇,相当于"双桥",简化为拓扑回路的边。因此,配合物1的骨架描述为sqc422拓扑网络。By using hydrothermal method, a cobalt complex, namely, [Co2（L）（Bipy）2]n, （1）, was synthesized based on flexible 1,3-bis [3,5-（dicarboxylate）phenoxy]-2-hydroxypropane （H4L） and 4,4＇ -bipyridine （Bipy）. The complex 1 was characterized by infra-red spectrum （IR）, UV-Vis spectrum, thermo-gravimetrie analysis （TGA）, single crystal X-ray diffraction, powder X-ray diffraction and elemental analysis. Complex 1 crystalizes in monoclinic system, space group C2/c. In complex 1, two six-coordinated cobalt atoms were connected by two bidentate carboxylic groups, forming an octahedral dimetallie cluster, which can be considered as a 6-connected node to connect four L ligand molecules and two other dimetallie clusters. The flexible tetracarboxylate ligand L can be considered as a tetrahedral 4-connected node to connect four dimetallie clusters. The two parallel Bipy molecules bridging two dimetallic clusters are transformed into edge during simplification. Thus, the framework of 1 features a sqc422 net. CCDC： 947285.
