چکیده
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 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), ...
