Novel hydrogen-bonded three-dimensional network complexes containing copper-pyridine-2,6-dicarboxylic acid

The novel complex (H3O)(2)[Cu(2,6-pydd)(2)].H2O (pydc=pyridinedicarboxylic acid) (1) has been synthesized in aqueous solution and characterized by single-crystal X-ray diffraction, elemental analyses and IR spectra. X-ray structural analysis revealed that the novel complex possesses both pi-pi stacking and hydrogen-bonding interactions for three-dimensional (3D) networks. Crystal data for 1: a = 13.454(3), b = 10.266(2), c = 13.783(3) Angstrom, alpha = 90.00, beta = 115.29(3), gamma = 90.00degrees, Z = 3, R-1 = 0.0423, wR(2) = 0.1217.
