Synthesis,Crystal Structure and Properties of a New Coordination Polymer Constructed with 3-（4-hydroxypyridinium-1-yl）phthalic Acid

A new nickel coordination polymer {[Ni(dpa)(bpe)(H2O)]2}n(1) has been hydro-thermally synthesized, and structurally characterized by UV spectroscopy, elemental analyses and single-crystal X-ray diffraction(H2dpa=3-(4-hydroxypyridinium-1-yl) phthalic acid, bpe=μ-1,2-di(4-pyridyl) ethylene). It crystallizes in the triclinic system, space group P1 with a=8.779(2), b=10.909(3), c=12.739(3), α=72.45(2), β=75.13(2), γ=86.47(2)°, V=1124.1(5) 3, Z=2, Mr=516.14, Dc=1.525 g/cm3, μ=0.912 mm-1, Rint=0.0532, F(000)=532, the final R=0.0523 and wR=0.1089 for 3949 observed reflections(I2σ(I)). The coordination around the Ni center is a distorted octahedron coordination geometry involving two protonated H2dpa ligands, two bpe ligands, and one coordinated H2O molecule. The dpa2- anion, as a bridging ligand, connects two Ni centers to form binuclear units, which are linked together by the bpe ligands to form two-dimensional layers, and the interlayer hydrogen bonding further extends the 2D sheet into a 3D supramolecular framework.
