The title compound, C14H18N2O2, contains two geometrically different molecules in the asymmetric unit: the basal plane of the cyclohexane chair and the N-[pyridin-3-ylmethylidene]methanamine moiety are oriented at dihedral angles of 71.77 (7)° and 83.42 (8)°. In the crystal, the molecules are linked by O—H⋯N hydrogen bonds, generating C(13) head-to-tail chains extending along the base vector . R22(26) ring motifs are formed due to the C—H⋯·O interactions that link neighbouring chains. There also exist π–π interactions [centroid–centroid separation = 3.6925 (12) Å] between the symmetry-related pyridine rings of one of the independent molecules.
