The tetradentate dianion in the title complex hydrate, [Cu(C23H28N2O4)]·H2O, provides the CuII atom with a cis-N2O2 donor set. There is a significant twist from a regular square-planar geometry with the dihedral angle formed between the two six-membered CuOC3N chelate rings being 32.14 (8)°. The water molecule forms hydrogen bonds to each of the coordinating O atoms of a given complex molecule. Supramolecular layers in the bc plane are formed in the crystal packing through C-HO and C-H interactions.
