| 摘 要： | A novel coordination polymer [Nd2（PDB）2（CH3COO）2（H2O）3] （H2PDB = pyridine3,4-dicarboxylic acid） has been synthesized by the reaction of Nd（CH3COO）3 with pyridine3,4-dicarboxylic acid under hydrothermal conditions. Elemental analysis, IR spectra and X-ray crystal structure analysis were carried out to determine the composition and crystal structure of the title complex which belongs to the triclinic system, space group P^-1 with a = 6.9409（14）, b = 7.5497（15）, c = 22.530（5）A, α = 84.79（3）, β = 88.15（3）, γ= 75.55（3）^o, C18H18N2O15Nd2, Mr = 790.82, Z = 2, V = 1138.5（4） A^3, Dc = 2.307 g/cm^3,μ = 4.593 mm^-1, -6≤h≤8, -5≤k ≤8, -26≤l≤ 26, F（000） = 760, Rint = 0.0298, R= 0.0314 and wR= 0.0695 （I〉 2σ（I））. Nd（1） and Nd（2） are linked into zigzag chains by carboxylate groups of acetate with interesting μ3-η^2：η^2 fashion. The zigzag chains are bridged by PDB to form a 2D framework, and a 3D supramolecular network is further constructed via π-π stacking.

| Abstract: | A novel coordination polymer [Nd2(PDB)2(CH3COO)2(H2O)3] (H2PDB = pyridine-3,4-dicarboxylic acid) has been synthesized by the reaction of Nd(CH3COO)3 with pyridine-3,4-dicarboxylic acid under hydrothermal conditions. Elemental analysis, IR spectra and X-ray crystal structure analysis were carded out to determine the composition and crystal structure of the title complex which belongs to the tdclinic system, space group P1 with a = 6.9409(14), b =7.5497(15), c = 22.530(5) A, α = 84.79(3), β = 88.15(3), γ = 75.55(3)°, C18H18N2O15Nd2, Mr=790.82, Z = 2, V = 1138.5(4) A3, Dc = 2.307 g/cm3 μ = 4.593 mm-1, -6≤h≤8, -5≤k ≤8,-26≤l≤26, F(000) = 760, Rint = 0.0298, R = 0.0314 and wR = 0.0695 (Ⅰ 20(Ⅰ)). Nd(1) and Nd(2) are linked into zigzag chains by carboxylate groups of acetate with interesting μ3-η2:η2 fashion. The zigzag chains are bridged by PDB to form a 2D framework, and a 3D supramolccular network is further constructed via π-π stacking. |
