A new three-dimensional coordination polymer {[Co(BPTC)0.5(bix)]′(H2O)}n (1, H4BPTC = 1,1′-biphenyl-2,2′,6,6′-tetracarboxylic acid, bix = 1,3-bis(imidazol-l-ylmethyl)-benzene) has been synthesized by the...A new three-dimensional coordination polymer {[Co(BPTC)0.5(bix)]′(H2O)}n (1, H4BPTC = 1,1′-biphenyl-2,2′,6,6′-tetracarboxylic acid, bix = 1,3-bis(imidazol-l-ylmethyl)-benzene) has been synthesized by the hydrothermal method and characterized by IR, elemental analysis, and single-crystal X-ray analysis. The crystal is of orthorhombic, space group Pbcn with a = 13.2975(10), b = 13.8424(12), c = 22.6367(17) A, CoC22H19N4Os, Mr = 478.34, V = 4166.7(6) A3, Dc = 1.525 g/cm^3, F(000) = 1968,μ = 0.867 mm^-1, S = 1.023 and Z = 8. The final R = 0.0683 and wR = 0.1529 for 3655 observed reflections with I 〉 20(I). In the title complex, the 2D Co-BPTC layer is formed through self-assembly of Co(II) ions and bridging BPTC4-ligands in a molar ratio of 2:1. The metal-organic lattice layers are further united together through the second bridging ligand bix to form a 3D metal-organic framework. The thermal stability of the title complex was studied by thermal gravimetric (TG) and differential thermal analysis (DTA).展开更多
