چکیده
In the asymmetric unit of the title compound, C(17)H(19)NO(3), there are three independent mol-ecules, which are align nearly parallel to each other and adopt the phenol-imine tautomeric form. In each mol-ecule, an intra-molecular O-H⋯N hydrogen bond results in the formation of an S(6) ring motif. The dihedral angles between the aromatic rings in the three independent mol-ecules are 13.55 (2), 21.24 (2) and 46.26 (1)°. C-H⋯π inter-actions are also observed in the crystal structure.

The title compound, C(25)H(26)N(2)O(4), exists in an E conformation with respect to each azomethine link. The two phenol-substituted benzene rings are twisted away from the plane of the diimine benzene ring by dihedral angles of 27.25 (5) and 56.67 (5)°. The mol-ecular structure is stabilized by intra-molecular O-H⋯N hydrogen bonds.

In the mol-ecule of the title compound, C(16)H(17)NO(3), the aromatic rings are oriented at a dihedral angle of 29.25 (8)°. An intra-molecular O-H⋯N hydrogen bond results in the formation of a nearly planar [maximum deviation 0.034 (13) Å] six-membered ring, which is oriented at dihedral angles of 0.91 (1) and 28.91 (12)° with respect to the aromatic rings. The title mol-ecule is a phenol-imine...

The title compound, C(16)H(17)NO(3), a Schiff base, is stabilized in the solid state in the phenol-imine tautomeric form, with the H atom located on the hydr-oxy O atom rather than on the N atom. This H atom is involved in a strong intra-molecular O-H⋯N hydrogen bond. The mol-ecule is almost planar, the angle between the benzene rings being 4.43 (13)°. C-H⋯π inter-actions are also present.
