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-H_2chdc)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(NO_3)_2·6H_2O合成了2个配合物[Co(BPYPY)_2(H_2O)_4]·(trans-chdc)·4H_2O(1)和{[Co(BPYPY)(H_2O)_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,P2_1/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。
Two compounds [Co(BPYPY)a(H2O)4] ·(trans-chdc)-4H20 (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.
