title: {4,4'-Dimethyl-2,2'-[2,2-dimethyl-propane-1,3-diylbis(nitrilo-methanylyl-idene)]diphenolato}copper(II) monohydrate.
abstract: The asymmetric unit of the title compound, [Cu(C(21)H(24)N(2)O(2))]·H(2)O, comprises half of a Schiff base complex and half of a water mol-ecule. 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 N(2)O(2) 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 mol-ecule that is hydrogen bonded to the coordinated O atoms links the mol-ecules via O-H⋯O inter-actions into chains parallel to [001]. The crystal structure is further stabilized by C-H⋯π inter-actions, and by π-π inter-actions involving inversion-related chelate rings [centroid-centroid distance = 3.480 (4) Å].
