| 摘 要： | 合成了一个新的Co2+配合物Co(bpdc)(H2O)2]n(bpdc=2,2’-bipyridyl-3,3’-dicarboxylato),并通过X-射线单晶衍射测定了其晶体结构.该配合物属单斜晶系,C2/c空间群,晶胞参数:a=11.676(3),b=8.070(2),c=13.028(4),α=γ=90°,β=100.303(3)°;Z=4,D=1.854mg/m3,V=1207.8(6)3;I>2σ(I)].该配合物为八面体结构,通过Co2+和一个配体bpdc的两个吡啶N原子、另外一个配体bpdc的两个不同羧基的O原子和两个配位水分子的O原子所构成.bpdc作为桥连配体,连接着两个中心Co2+,构成一维无线链,进而通过氢键形成二维网状结构.

| Abstract: | A new cobalt （Ⅱ） complex, Co （bpdc） （ H2O） 2 ] n （ bpdc = 2,2＇ - bipyridyl - 3, 3＇ - dicarboxylato）, has been synthesized and its structure determined by X-ray diffraction. The crystal structure of complex belong to Monoclinic system, space group C2/c with a=11.676（3）A,b=8.070（2）A,c=13.028（4）A,α=γ=90°,β=100.303（3）°;Z=4,D=1.854mg/m^3,V=1207.8（6）A^3;I〉2σ（I）]. In the complex, each Co^2＋ is octahedrally coordinated by two chelating pyridyl N atoms from one ligand （bpdc） , two chelating carboxyl O atoms from different carboxylate groups of another ligand （bpdc） , and two coordination water molecules. The pbde as a bridge ligand links two cobalt （Ⅱ） centers to form one-dimensional chain, and via hydrogen bonds to structure two- dimensional reticulation. |
