Mol-ecules of the title compound, [Cu(C(21)H(17)N(3)O(4))(H(2)O)], lie across a crystallographic mirror plane. The Cu(II) atom is five-coordinated in a distorted square-pyramidal environment by two phenolate O atoms and two imine N atoms of the tetra-dentate Schiff base anion in the basal plane and one water mol-ecule in the apical position. Because of symmetry, the pyridine N atom and the corresponding C atom at the 4-position of the pyridine ring are disordered. The crystal packing can be described as being composed of alternating layers stacked along [001]. Intra-molecular C-H⋯N and inter-molecular C-H⋯O and O-H⋯O hydrogen-bonding inter-actions, as well as C-H⋯π and π-π stacking inter-actions [shortest centroid-centroid distance = 3.799 (8) Å and inter-planar distance = 3.469 (2) Å] are observed.
标题化合物[Cu(C₂₁H₁₇N₃O₄)(H₂O)]的分子位于一个晶体学镜面平面上。Cu(II)原子在一个扭曲的四方锥环境中通过两个酚氧原子和两个亚胺氮原子在基面的四齿席夫碱阴离子以及一个位于顶端位置的水分子进行五配位。由于对称性，吡啶N原子和吡啶环4位的相应C原子是无序排列的。晶体堆积可以描述为由沿[001]堆叠的交替层组成。观察到分子内C-H⋯N和分子间C-H⋯O以及O-H⋯O氢键相互作用，以及C-H⋯π和π-π堆积相互作用[最短质心-质心距离 = 3.799 (8) Å，平面间距离 = 3.469 (2) Å]。
