Six novel coordination polymers based on a multifunctional ligand, 5,5鈥?(1,2-ethynyl)bis-1,3-benzenedicarboxylic (H4EBDC), namely, |(C3H7NO)2(H2O)7(C2H5OH)3|[Zn2(C18H6O8)(C10H8N2)2] (1), |(C3H7NO)3(H2O)30(CH3CN)2|[Zn6(C18H6O8)3(C6H12N2O2)2] (2), |(C3H7NO)2(H2O)2(H3O)2|[Cd3(C18H6O8)2] (3), |(C3H7NO)|[Mn(C18H8O8)(C3H7NO)2] (4), |(C3H7NO)2(H2O)(C2H7N)3|[Mn6(C18H7O8)4(H2O)8] (5), and [Mn2(C18H6O8)(C3H7NO)2] (6), have been constructed under solvothermal conditions and structurally characterized by single-crystal X-ray diffraction. In these compounds, the ligand, H4EBDC, exhibits different coordination modes and conformations, constructing various architectures by bridging a variety of metal ions or polynuclear clusters. Compound 1 forms a three-dimensional (3D) FSC network constructed from two-dimensional (2D) layer motifs joined by EBDC4鈥?/sup> and 4,4鈥?bipyridine bridges. Compound 2 possesses an NbO topology by linking Zn2(CO2)4 units with the ligand, coordinated amine molecules fill the pores, while compound 3 exhibits a 3D FLU network with Cd2+ as the cation and features an infinite framework built from tricadmium clusters. Compound 4 is based on PtS net, constructed of 4-connected rectangular H4EBDC units with tetrahedral monometallic Mn(CO2)4 nodes. Compound 5 is composed of 2D layers with (3,6)-connected KGD topology, and compound 6 consists of a 3D PtS-X network, built by bridging a metal chain with the ligand. The structures of these compounds have been discussed together with their corresponding properties, such as gas storage, separation, and magnetic properties.
