摘要
采用水热法合成了两个新颖的配合物{[Ni(H2qptc)(4,4′-bpy)(H2O)2].2(H2O)}n(1)和[Zn2(H2O)2(qptc)(4,4′-bpy)]n(2)(H4qptc:三联苯-2,5,2′,5′-四羧酸,4,4′-bpy:4,4′-联吡啶),并对其进行了元素分析、热重、红外光谱和、磁性和X-射线单晶衍射测定。化合物1和2都是三维结构,分别显示(65.8)-cds、(42.6)2(43.62.8)(45.64.8)2.拓扑结构。
Solvothermal reactions of aromatic terphenyl-2,5,2′,5′-tetracarboxylic acid(H4qptc) ligand and transitionalmetal cations of M Ⅱ(M=Ni,Zn) in the presence of 4,4′-bipyridine(4,4′-bpy) afford two new coordinationpolymers(CPs),namely,{[Ni(H2qptc)(4,4′-bpy)(H2O)2].2(H2O)}n(1) and [Zn2(H2O)2(qptc)(4,4′-bpy)]n(2).Theirstructures have been determined by single-crystal X-ray diffraction analyses and further characterized byelemental analyses,TGA,and magnetism.In 1,the H2qptc2-acts as a Z-shaped ligand linking the NiⅡ centers toa 1D zigzag polymeric [Ni(H2qptc)]n chain,based on which a unique 3D 4-connected framework with distorted(65.8)-cds topology is formed.For 2,the qptc4-acts as a H-shaped ligand linking the ZnⅡ centers together to forma 2D polymeric [Zn(qptc)]n layer,which is further connected by 4,4′-bpy,thus generating a 3D(3,4)-connectednetwork with the Schlfli symbol of (42.6)2(43.62.8)(45.64.8)2.
