Solvothermal reaction of aromatic terphenyl-2,5,2',5'-tetracarboxylic acid (Hnqptc) ligand and the transitional metal cation of Mn11 in the presence of 3-(2-pyridyl)pyrazole (pp) affords one new coordination polymer, [Mn(qptc)0.5(pp)2]n·n(H2O) (1). The structure has been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses, IR, TGA, and magnetism. The carboxyl groups of qptc4 exhibit a μ1-η1:η0 coordination mode, and the qptc4- acts as a H-shaped ligand linking the Mn11 centers together to form a 2D polymeric [Mn(qptc)0.5]n layer. The crystal of 1 crystallizes in orthorhombic, space group Pbca with a = 9.3119(12), b = 20.848(3), c = 26.134(3) A, V= 5073.4(11) A3, Z= 8, C27HIgMnN6O5,Mr=562.42, Dc = 1.473 g/cm3, F(000) = 2304 and μ(MoKa) = 0.571 mm-1. The final R = 0.0468 and wR = 0.1196 for 4429 observed reflections with I 〉 2σ(I) and R = 0.0797 and wR = 0.1383 for all data. 展开更多

Solvothermal reaction of aromatic 2,6-bis(4'-carboxyphenyl)-4-phenylpyridine (H2bpp) ligand and nickel cation in the presence of 1,10-phenanthroline (phen) affords one new coordination polymer (CPs), [Ni(bpp)(phen)(H20]n (1). The structure has been determined by single-crystal X-ray diffraction analysis and further characterized by elemental analyses, IR, PXRD and luminescence. Ions of Nin in 1 are linked via bpp2 to form chains, which are further connected through non-covalent interactions (including O-H...O and n...zr interactions) to form a 3D packing diagram.

Their structures have been determined by single- crystal X-ray diffraction analyses, elemental analyses, IR spectra, and powder X-ray diffraction (PXRD) analyses. In compound 1, the CdII cations are linked by bpp2- to form one ladder structure, based on which a 3D network is constructed with the help of non-covalent interactions. The topology of 2 is a 3D (3,4,5)-connected framework with the Point Schl?fli symbol of (42.6)2(43.62.8)(45.64.8)2. Compound 3 shows an unprecedented 3D (4,4)-connected framework with the Point Schl?fli symbol of (64.82)2(65.8). Moreover, the luminescent property of 1 has been investigated. 展开更多
