The whole mol-ecule of the title Schiff base compound, C34H28N2O4, is generated by mirror symmetry, with the mirror bis-ecting the central benzene ring. It was synthesized via the condensation reaction of 1,2-di-amine-benzene with 4-benz-yloxy-2-hy-droxy-benzaldehyde. The mol-ecule is V-shaped and there are two intra-molecular O-H⋯N hydrogen bonds present forming S(6) ring motifs. The configuration about the C=N imine bonds is E. The central benzene ring makes dihedral angles of 41.9 (2) and 43.6 (2)° with the phenol ring and the outer benz-yloxy ring, respectively. The latter two rings are inclined to each other by 84.4 (2)°. In the crystal, mol-ecules are linked by C-H⋯π inter-actions, forming layers lying parallel to the ab plane. The Hirshfeld surface analysis and the two-dimensional fingerprint plots confirm the predominance of these inter-actions in the crystal structure. The anti-oxidant capacity of the compound was determined by the cupric reducing anti-oxidant capacity (CUPRAC) process.
