摘　　要：A new three-dimensional supramolecule composed of copper-Schiff base complex, [Cu（naphdien）]Cl·H2O, where naphdien is Schiff base of 2-hydroxy-1-naphthaldehyde and diethylenetriamine, has been synthesized and determined by single-crystal X-ray diffraction. It belongs to the monoclinic system, space group P21/c, with a = 7.3490（15）, b = 7.0847（16）, c = 30.845（3）A, β= 95.33（3）°, V = 1599.0（5）A3, Z = 4, C15 H20ClCuN3O2, Mr = 373.33, De = 1.551 g/cm3, μ = 1.543 mm^-1, F（000） = 772, R = 0.0536 and wR = 0.0927 for 2788 unique reflections with 1659 observed ones （I 〉2σ（I））. In the crystal structure, mononuclear units [Cu（naphdien）]Cl·H2O are linked into a two-dimensional framework via strong hydrogen bonds, and extended into a three-dimensional supramolecular structure through π-π stacking interactions.A new three-dimensional supramolecule composed of copper-Schiff base complex, [Cu（naphdien）]Cl·H2O, where naphdien is Schiff base of 2-hydroxy-1-naphthaldehyde and diethylenetriamine, has been synthesized and determined by single-crystal X-ray diffraction.
