摘　　要：The complexes of [Cu（bpy）（H2O）（CBA）2]n 1 and [Cu（phen）（H2O）（CBA）2]·H2O 2 based on p-cyanobenzoic acid （HCBA） have been synthesized in aqueous ethanolic solution at room temperature. The single-crystal X-ray diffraction studies demonstrated that complex 1 crystallizes in orthorhombic and complex 2 is of triclinic system. The results indicate the complex 1 shows a 1D chain structure bridged bytwo carboxylic oxygen atoms from CBA–, and complex 2 is a mononuclear structure. Through intermolecular hydrogen bonding and π···π stacking interactions, the complexes are assembled into supramolecular structures.Complex 1 has been characterized by magnetic measurements. Themagnetic measurement indicates that weak ferromagnetic interaction （zJ＇ = 0.038（5）） between the Cu^2＋ ions is dominant in the structure. The IR spectrum and results of thermal and elemental analyses are also presented.The complexes of [Cu（bpy）（H2O）（CBA）2]n 1 and [Cu（phen）（H2O）（CBA）2]·H2O 2 based on p-cyanobenzoic acid （HCBA） have been synthesized in aqueous ethanolic solution at room temperature.
