The asymmetric unit of the binuclear title compound, [Cu(CHO)(HO)], comprises two halves of diaquatetra-kis-(μ-3-meth-oxy-benzoato-κ : )dicopper(II) units. The paddle-wheel structure of each complex is completed by application of inversion symmetry, with the inversion centre situated at the midpoint between two Cu atoms in each dimer. The two Cu atoms of each centrosymmetric dimer are bridged by four 3-meth-oxy-benzoate anions resulting in Cu⋯Cu separations of 2.5961 (11) and 2.6060 (12) Å, respectively. The square-pyramidal coordination sphere of each Cu atom is completed by an apical water mol-ecule. Inter-molecular O-H⋯O hydrogen bonds of weak nature link the complexes into layers parallel to (100). The three-dimensional network structure is accomplished by C-H⋯O hydrogen bonds inter-linking adjacent layers.
双核标题化合物[Cu(CHO)(HO)]的不对称单元由二水四（μ-3-甲氧基苯甲酸根-κ : ）二铜（II）单元的两个半部分组成。每个配合物的桨轮结构通过反演对称性得以完善，反演中心位于每个二聚体中两个铜原子之间的中点。每个中心对称二聚体的两个铜原子由四个3-甲氧基苯甲酸根阴离子桥连，导致铜⋯铜间距分别为2.5961 (11) 和2.6060 (12) Å。每个铜原子的四方锥配位球由一个顶端水分子完成。弱性质的分子间O-H⋯O氢键将配合物连接成平行于(100)的层。三维网络结构通过连接相邻层的C-H⋯O氢键实现。
