AbstractA novel coordination polymer Nd-2(PDB3)(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 carried out to determine the composition and crystal structure of the title complex which belongs to the triclinic system, space group Pi with a = 6.9409(14), b = 7.5497(15), c = 22.530(5) angstrom, a = 84.79(3), beta = 88.15(3), gamma = 75.55(3)degrees, C18H18N2O15Nd2, M-r = 790.82, Z = 2, V = 1138.5(4) angstrom(3), D-c = 2.307 g/cm(3), mu = 4.593 mm(-1), -6, 2 sigma(I)). Nd(1) and Nd(2) are linked into zigzag chains by carboxylate groups of acetate with interesting mu(3)-eta(2):eta(2) fashion. The zigzag. chains are bridged by PDB to form a 2D framework, and a 3D supramolecular network is further constructed via pi-pi stacking.
Other AbstractA novel coordination polymer Nd_2(PDB)_2(CH_3COO)_2(H_2O)_3 (H_2PDB = pyridine3,4-dicarboxylic acid) has been synthesized by the reaction of Nd(CH_3COO)_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, C_(18)H_(18)N_2O_(15)Nd_2, M_r = 790.82, Z = 2, V = 1138.5(4) A~3, D_c = 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.
