Mol­ecules of the title compound, [Cu(C21H17N3O4)(H2O)], lie across a crystallographic mirror plane. The CuII atom is five-coordinated in a distorted square-pyramidal environment by two phenolate O atoms and two imine N atoms of the tetra­dentate Schiff base anion in the basal plane and one water mol­ecule 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]. Intra­molecular C—H⋯N and inter­molecular C—H⋯O and O—H⋯O hydrogen-bonding inter­actions, as well as C—H⋯π and π–π stacking inter­actions [shortest centroid–centroid distance = 3.799 (8) Å and inter­planar distance = 3.469 (2) Å] are observed.
