title: {4,4'-Dimeth-oxy-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(4))]·H(2)O, comprises half of a Schiff base complex and a water mol-ecule. The Cu(II) atom, water mol-ecule and one C atom of the central propyl-ene segment are located on a twofold rotation axis. The geometry around the Cu(II) atom is distorted square-planar, supported by the N(2)O(2) donor atoms of the coordinating ligand. The dihedral angle between the symmetry-related benzene rings is 42.56 (19)°. In the crystal, O-H⋯O hydrogen bonds involving the water mol-ecule make an R(2) (1)(6) ring motif. Complex mol-ecules are linked into a chain along the c axis via C-H⋯O inter-actions.
