{4,4′-Dimethyl-2,2′-[2,2-dimethyl­propane-1,3-diylbis(nitrilo­methanylyl­idene)]diphenolato}copper(II) monohydrate

The asymmetric unit of the title compound, [Cu(C₂₁H₂₄N₂O₂)]·H₂O, comprises half of a Schiff base complex and half of a water mol­ecule. The whole compound is generated by crystallographic twofold rotation symmetry. The geometry around the Cu^II atom, located on a twofold axis, is distorted square-planar, which is supported by the N₂O₂ donor atoms of the coordinating Schiff base ligand. The dihedral angle between the symmetry-related benzene rings is 47.5 (4)°. In the crystal, the water mol­ecule that is hydrogen bonded to the coordinated O atoms links the mol­ecules via O—H...O inter­actions into chains parallel to [001]. The crystal structure is further stabilized by C—H...π inter­actions, and by π–π inter­actions involving inversion-related chelate rings [centroid–centroid distance = 3.480 (4) Å].
