A novel three-dimensional supramolecular framework with one-dimensional channels:: synthesis and crystal structure of [Cu(DPC)(H2O)3] (H2DPC = Pyridine-2,6-dicarboxylic acid)

A new supramolecular compound formulated [Cu(DPC)(H2O)(3)] (H2DPC = Pyridine-2,6-dicarboxylic acid) was synthesized under mild conditions and characterized by elemental analyses, IR spectrum, thermogravimetric (TG) analysis and single-crystal X-ray diffraction. The crystal crystallizes in the monoclinic system, space group of C2/c with a = 6.4448(9) Angstrom, b = 23.192(3) Angstrom, c = 6.9139(12) Angstrom, alpha = 90degrees, beta = 106.622(11)degrees, gamma = 90degrees, V = 990.2(3) Angstrom(3), Z = 4, R = 0.0580, and wR(2) = 0.1522. The compound exhibits an interesting three-dimensional (3D) supramolecular framework structure with one-dimensional channels, which is constructed by extensive hydrogen-bonding and pi-pi stacking interactions.
