摘      要：A hydrogen-bonded supermolecular compound [（C6H5N2O）3·Cu1.5]·6H2O was synthesized from picolinamide and Cu（NO3）2·6H2O at the presence of sodium pyrophosphate decahydrate. It crystallizes in triclinic, space group P1^- with a = 1.05947（8）, b = 1.09130（8）, c = 1.11456（8） nm, a = 67.8460（10）, β= 84.497（1）, γ = 74.6210（10）°, C18H27Cu1.5N6O9, Mr = 566.77, V = 1.15077（15） nm^3, Z = 2, Dc = 1.636 g/cm^3, F（000） = 585,μ= 1.461 mm^-1, R1 = 0.0278 and wR2 = 0.0749. In the complex, the Cu（Ⅱ） ion reveals a distorted tetradentate plane-tetragonal geometry. The structure consists of neutral two-dimensional layers via hydrogen bonds O-H...O and N-H...O between the molecules, and the layers are connected by weak interactions of the Cu-Cu, Cu-N, π-π and hydrogen bonds to form a three-dimensional network structure.
