A new ternary copper（Ⅱ） complex, [C43H27Cu2N7O5][C14H6CuN2O8]＇6.5H2O, has been synthesized by the reaction of copper sulfate, 2,6-pyridinedicarboxylic acid and 1,10- phenanthroline （phen）, and characterized by elemental analysis, IR, UV and X-ray single-crystal diffraction. It crystallizes in triclinic, space group P1, with a = 14.379（5）, b = 15.510（5）, c = 15.835（6） A, a = 78.567（6）, β = 63.594（6）, y = 81.287（6）°, V= 3092.1（19） A3, C57H46Cn3N9O19.5, Mr = 1359.54, Z = 2, Dc = 1.446 Mg/m3, λ（MoKa） = 0.71073 A,μ = 1.101 mm^-1, F（000） = 1362, S = 1.071, the final R = 0.0718 and wR = 0.11960 for 10705 observer reflections （I 〉 2σ（I））. The structure unit of the title complex consisfs of a mononuclear part and a di-nuclear part, and the three copper ions show three coordination modes. Each 6-coordinated geometry of the Cu atom is a distorted octahedral coordination geometry. The 3D supramolecular system is formed by the hydrogen bond O-H-O and π-π stacking interaction between neighboring single cells. The antibacterial activity of the title complex is also studied.
