Synthesis and Crystal Structure of [Zn(HPDB)_2(H_2O)_2]_n · 2nDMSO · 2nH_2O (H_2-PDB = Pyridine-3,4-dicarboxylic Acid)

摘要

The title complex [Zn(HPDB)_2(H_2O)_2]_n · 2nDMSO · 2nH_2O (H_2-PDB is pyridine-3, 4-dicarboxylic acid and DMSO the dimethyl sulphoxide) was synthesized under traditional solution condition. Its crystal (C_(18)H_(28)N_2O_(14)S_2Zn) belongs to monoclinic system, space group P2_1/c with a = 8.2791(6),b = 12.5495(10), c= 13.6519(11) A, β = 105.294(2)°, V= 1368.18(18) A~3, Z= 2, M_r = 625.91, D_x = 1.514 g/cm~3, μ= 1.117 mm~(-1), F(000) = 648, R - 0.0654 and wR = 0.1654 for 2414 observed reflections (I > 2σ(I)). It has a 2-D planar network, in which the Zn atom is six-coordinated and hydrogen bonds between carboxylate groups, DMSO and water molecules result in the final 3D structure.
