Abstract:
In the mol-ecule of the title compound, C15H15NO 2, the aromatic rings are oriented at a dihedral angle of 15.46 (6)°. An intra-molecular O - H⋯N hydrogen bond results in the formation of a nearly planar six-membered ring [maximum deviation of 0.035 (5) Å for the N atom] which is almost coplanar with the adjacent ring, making a dihedral angle of 0.8 (3)°. The title organic mol-ecule is a phenol-imine tautomer, as evidenced by the C - O, C - N and C - C bond lengths. Mol-ecules are linked by inter-molecular C - H⋯O hydrogen bonds that generate a C(5) chain. C - H⋯π and π-π inter-actions exist in the structure. The π-π inter-action occurs between the phenol ring and its symmetry equivalent at (1 - x, 1 - y, -z), with a centroid-centroid distance of 3.727 (7) Å and a plane-to-plane separation of 3.383 (5) Å, resulting in an offset angle of 24.82 (1)°. © 2009.
