摘　　要：A new complex, [Cu（HL）（phen）（H2O）]·4H2O（1, H3L·HCl = 5-（（4-carboxypiperidin-1-yl）methyl）isophthalic acid hydrochloride, phen = 1,10-phenanthroline）, has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and PXRD. Complex 1 crystallizes in monoclinic, space group P21/c with a = 14.5520（14）, b = 12.6659（12）, c = 15.5006（14） A, β = 97.224（2）o, V = 2834.3（5） A3, Z = 4, C27H33N3O11 Cu, Mr = 639.10, Dc = 1.498 g/cm3, μ = 0.837 mm-1, S = 1.047, F（000） = 1332, the final R = 0.0423 and w R = 0.1118 for 18772 observed reflections（I 〉 2σ（I））. The compound is a Cu（Ⅱ） centre mononuclear molecule in the asymmetric unit. The independent binuclear [Cu2（HL）2（phen）2] units are bridged to form a three-dimensional（3D） supramolecular polymer by extensive hydrogen bonds and π-π non-covalent bonding interactions. Moreover, thermogravimetric（TG） analysis and gas adsorption property of 1 were also discussed.A new complex, [Cu（HL）（phen）（H2O）]·4H2O（1, H3L·HCl = 5-（（4-carboxypiperidin-1-yl）methyl）isophthalic acid hydrochloride, phen = 1,10-phenanthroline）, has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and PXRD.
