In the title compound, [Cu(CH(3)COO)(2)(C(18)H(16)N(2)O(2))]·4H(2)O, the Cu(II) ion is six-coordinated in a Jahn-Teller-distorted octa-hedral geometry environment defined by four O atoms and two N atoms. A chain structure along [100] is built up by inter-molecular O-H⋯O hydrogen bonds involving the uncoordinated water mol-ecules.
