| 摘要: 用3,5-双(4-吡啶基)-吡啶(BPYPY)分别与反式-1,4-环己烷二甲酸(trans-H2chdc)和4,4'-联苯醚二甲酸(H2oba)组成混合配体,用温和的溶剂热法与Co(NO3)2·6H2O合成了2个配合物[Co(BPYPY)2(H2O)4]·(trans-chdc)·4H2O (1)和{[Co(BPYPY)(H2O)4]·(oba)}n(2),利用X射线单晶衍射、元素分析对它们进行了表征。结果显示,配合物1为单核结构,属于单斜晶系,P21/n空间群;配位聚合物2是一维链通过O-H…O氢键形成的三维超分子结构,属于正交晶系,Pccn空间群。 |

| Abstract: Two compounds[Co(BPYPY)2(H2O)4]·(trans-chdc)·4H2O (1) and {[Co(BPYPY)(H2O)4]·(oba)}n (2) were synthesized by mild hydrothermal method using two mixed-ligands consisting of 3,5-bis(4-pyridyl)-pyridine (BPYPY), trans-1,4'-cyclohexanedicarboxylic acid (trans-H2chdc), 4,4'-oxydibenzoic acid (H2oba) and Co(NO3)2·6H2O. The complexes were characterized by elemental analysis and their crystal structures were determined by single-crystal X-ray diffraction. Structural analyses show that compound 1 is mononuclear complex, and crystallizes in the monoclinic system, space group P21/n; compound 2 is a 1D chain and further extended via O-H…O interaction to generate infinite 3D supramolecular structure, and crystallizes in the orthorhombic system, space group Pccn. |
