In the title complex, [Cu(C(23)H(28)N(2)O(4))]·H(2)O, the Cu(II) ion has a distorted planar geometry, coordinated by the N(2)O(2) unit of the tetra-dentate Schiff base ligand. The asymmetric unit comprises one complex mol-ecule and a water mol-ecule of crystallization. The water H atoms form bifurcated O-H⋯(O,O) inter-molecular hydrogen bonds with the O atoms of the phenolate and eth-oxy groups with R(1) (2)(5) and R(1) (2)(6) ring motifs, which may, in part, influence the mol-ecular configuration. The dihedral angle between the two O-Cu-N coordination planes is 31.02 (6)° and the dihedral angle between the two benzene rings is 34.98 (7)°. In the crystal structure, mol-ecules are linked together by inter-molecular C-H⋯O inter-actions, forming extended chains along the a axis. The crystal structure is further stabilized by inter-molecular C-H⋯π and π-π [centroid-centroid = 3.5068 (13) Å] inter-actions.
在标题配合物[Cu(C₂₃H₂₈N₂O₄)]·H₂O中，Cu(II)离子具有扭曲的平面几何构型，由四齿席夫碱配体的N₂O₂单元配位。不对称单元包含一个配合物分子和一个结晶水分子。水分子的H原子与酚盐和乙氧基的O原子形成分叉的O—H⋯(O,O)分子间氢键，其具有R(1) (2)(5)和R(1) (2)(6)环基序，这可能部分影响分子构型。两个O—Cu—N配位平面之间的二面角为31.02 (6)°，两个苯环之间的二面角为34.98 (7)°。在晶体结构中，分子通过分子间C—H⋯O相互作用连接在一起，沿a轴形成延伸链。晶体结构通过分子间C—H⋯π和π—π[质心 - 质心距离 = 3.5068 (13) Å]相互作用进一步稳定。
