The asymmetric unit of the title compound, [Co(C(23)H(28)N(2)O(4))(C(9)H(9)O(3))]center dot C(2)H(5)OH center dot H(2)O, comprises one complex molecule, a water molecule of crystallization and an ethanol molecule of crystallization, which is disordered over two positions with a ratio of refined site occupancies of 0.567 (10):0.433 (10). The Co(III) ion is in a slightly distorted octahedral geometry involving an N(2)O(2) atom set of the tetradenate Schiff base ligand and two O atoms of 2-ethoxy-6-formylphenolate. The H atoms of the water molecule act as donors in the formation of bifurcated intermolecular O-H center dot center dot center dot(O, O) hydrogen bonds with the O atoms of the hydroxy and ethoxy groups with R(1)(2)(5) ring motifs, which may influence the molecular conformation. The crystal structure is further stabilized by intermolecular O-H center dot center dot center dot O and C-H center dot center dot center dot O interactions.
