{6,6'-Dieth-oxy-2,2'-[2,2-dimethyl-propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenolato}copper(II) monohydrate.

In the title complex, [Cu(C(23)H(28)N(2)O(4))]·H(2)O, the Cu(II) ion has a distorted planar geometry, coordinated by the N(2)O(2) unit of the tetra-dentate Schiff base ligand. The asymmetric unit comprises one complex mol-ecule and a water mol-ecule of crystallization. The water H atoms form bifurcated O-H⋯(O,O) inter-molecular hydrogen bonds with the O atoms of the phenolate and eth-oxy groups with R(1) (2)(5) and R(1) (2)(6) ring motifs, which may, in part, influence the mol-ecular configuration. The dihedral angle between the two O-Cu-N coordination planes is 31.02†(6)° and the dihedral angle between the two benzene rings is 34.98†(7)°. In the crystal structure, mol-ecules are linked together by inter-molecular C-H⋯O inter-actions, forming extended chains along the a axis. The crystal structure is further stabilized by inter-molecular C-H⋯π and π-π [centroid-centroid = 3.5068†(13)†à ] inter-actions.
