Bottom Line: An intra-molecular O-H⋯N hydrogen bond forms a six- membered ring, producing an S(6) ring motif.The two benzene rings are almost perpendicular to each other, making a dihedral angle of 85.00 (2)°.The mol-ecules also adopt a zigzag arrangement along the c axis.

ABSTRACT
In the crystal structure, the title Schiff base compound, C(21)H(26)N(2)O(4), has twofold rotation symmetry. The imino group is coplanar with the aromatic ring. An intra-molecular O-H⋯N hydrogen bond forms a six- membered ring, producing an S(6) ring motif. The two benzene rings are almost perpendicular to each other, making a dihedral angle of 85.00 (2)°. The meth-oxy group is approximately coplanar with the benzene ring, with a C-O-C-C torsion angle of 2.34 (12)°. Neighbouring mol-ecules are linked together by weak inter-molecular C-H⋯O hydrogen bonds and a C-H⋯π inter-action, forming a sheet parallel to the ab plane. The mol-ecules also adopt a zigzag arrangement along the c axis.
