ABSTRACT: In the title complex, [Co(C(22)H(24)N(2)O(4))]·H(2)O, the Co(II) atom is in an almost square-planar coordination environment involv-ing two O and two N atoms from the Schiff base ligand. A water mol-ecule cocrystallizes with the coordination compound and may be held in the crystal by O-H⋯O hydrogen bonds. Heteroatomic π-π ring inter-actions may be present between symmetry-related complexes, with centroid-centroid distances of 3.5661 (8) Å.
