3-[(E)-(Pyridin-3-ylimino)methyl]phenol

Two independent molecules are present in the asymmetric unit of the title compound, C12H10N2O, in which the 3-hydroxybenzaldehyde and the pyridin-3-amine units are almost planar [r.m.s. deviations of 0.0236 and 0.0116Å, respectively, in one molecule and 0.0245 and 0.0162Å, respectively, in the other] and are oriented at dihedral angles of 7.21 (7) and 14.77 (7)°. In the crystal, molecules of the same type form inversion dimers via pairs of O—H...N hydrogen bonds, forming R22(20) ring motifs. There exist π–π interactions between the benzene and pyridine rings of molecules of the same type with centroid–centroid distances of 3.7127 (10) and 3.8439 (10) Å
