Bottom Line: The dihedral angles between the benzene rings in the two mol-ecules are 53.64 (17) and 51.93 (17)°.Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs.The N atoms are also in close proximity to the H atoms of the dimethyl-propane groups, with H⋯N distances between 2.54 and 2.75 Å.

ABSTRACT
The title Schiff base compound, C(21)H(26)N(2)O(4), exhibits two crystallographically independent mol-ecules in the asymmetric unit with similar conformations. The imino groups are coplanar with the benzene rings; the maximum deviations of the N atoms from the planes comprising the benzene rings and the imino groups are -0.037 (4), 0.013 (4), -0.021 (5), and 0.008 (5) Å. The dihedral angles between the benzene rings in the two mol-ecules are 53.64 (17) and 51.93 (17)°. Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. The N atoms are also in close proximity to the H atoms of the dimethyl-propane groups, with H⋯N distances between 2.54 and 2.75 Å. The crystal structure is further stabilized by weak inter-molecular C-H⋯O hydrogen bonds, weak inter-molecular C-H⋯π inter-actions and π-π contacts involving the imine C atom and two C atoms from the adjacent benzene rings.
