| Abstract: Solvothermal reactions of aromatic terphenyl-2,5,2′,5′-tetracarboxylic acid (H4qptc) ligand and transitional metal cations of MⅡ (M=Ni, Zn) in the presence of 4,4′-bipyridine (4,4′-bpy) afford two new coordination polymers (CPs), namely, {[Ni(H2qptc)(4,4′-bpy)(H2O)2]·2(H2O)}n(1) and [Zn2(H2O)2(qptc)(4,4′-bpy)]n(2). Their structures have been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses, TGA, and magnetism. In 1, the H2qptc2- acts as a Z-shaped ligand linking the NiⅡ centers to a 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 form a 2D polymeric [Zn(qptc)]n layer, which is further connected by 4,4′-bpy, thus generating a 3D (3,4)-connected network with the Schl?fli symbol of (42.6)2(43.62.8)(45.64.8)2.
