The reaction of Cu(NO)·3HO with 2,4'-oxybis(benzoic acid) and 4,4'-bipyridine under hydrothermal conditions produced a new mixed-ligand two-dimensional copper(II) coordination polymer, namely poly[[(μ-4,4'-bipyridine-κN,N')[μ-2,4'-oxybis(benzoato)-κO,O:O,O]copper(II)] monohydrate], {[Cu(CHO)(CHN)]·HO}, which was characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis and single-crystal X-ray diffraction. The X-ray diffraction crystal structure analysis reveals that the Cu ions are connected to form a two-dimensional wave-like network through 4,4'-bipyridine and 2,4'-oxybis(benzoate) ligands. The two-dimensional layers are expanded into a three-dimensional supramolecular structure through intermolecular O-H...O and C-H...O hydrogen bonds. Furthermore, magnetic susceptibility measurements indicate that the complex shows weak antiferromagnetic interactions between adjacent Cu ions.
在水热条件下，硝酸铜三水合物与2,4'-氧联二苯甲酸和4,4'-联吡啶反应生成了一种新型的混合配体二维铜（II）配位聚合物，即聚[[(μ-4,4'-联吡啶-κN,N')[μ-2,4'-氧联二苯甲酸根-κO,O:O,O]铜（II）]一水合物]，{[Cu(C₁₄H₈O₄)(C₁₀H₈N₂)]·H₂O}，通过元素分析、红外光谱、热重分析和单晶X射线衍射对其进行了表征。X射线衍射晶体结构分析表明，铜离子通过4,4'-联吡啶和2,4'-氧联二苯甲酸配体连接形成二维波浪状网络。二维层通过分子间的O-H...O和C-H...O氢键扩展为三维超分子结构。此外，磁化率测量表明该配合物在相邻铜离子之间表现出弱反铁磁相互作用。
