In the title complex, [Cu(C(12)H(6)N(2)O(5))(H(2)O)], the Cu(II) ion is in a slightly distorted square-pyramidal coordination environment with two N and two O atoms from a 6,6'-oxydipicolinate ligand occupying the basal plane and a water ligand in the apical site. The dihedral angle between the two pyridine rings is 5.51 (6)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link mol-ecules into a two-dimensional network. In addition, weak inter-molecular C-H⋯O and C=O(lone pair)⋯π(ring) inter-actions, with O⋯ring-centroid distances of 3.697 (4) and 3.094 (4) Å, provide additional stabilization.
在标题配合物[Cu(C₁₂H₆N₂O₅)(H₂O)]中，Cu(II)离子处于略微扭曲的四方锥配位环境中，来自6,6'-氧化二吡啶甲酸配体的两个N原子和两个O原子占据基面，一个水配体位于顶点位置。两个吡啶环之间的二面角为5.51 (6)°。在晶体结构中，分子间的O—H⋯O氢键将分子连接成二维网络。此外，弱的分子间C—H⋯O和C=O(孤对)⋯π(环)相互作用，其O⋯环心距离分别为3.697 (4) Å和3.094 (4) Å，提供了额外的稳定性。
