Crystal structure, Hirshfeld surface analysis and anti­oxidant capacity of 2,2′-{(1E,1′E)-[1,2-phenyl­enebis(aza­nylyl­idene)]bis­(methanylyl­idene)}bis­(5-benz­yloxy)phenol

The whole mol­ecule of the title Schiff base compound, C(34)H(28)N(2)O(4), is generated by mirror symmetry, with the mirror bis­ecting the central benzene ring. It was synthesized via the condensation reaction of 1,2-di­amine­benzene with 4-benz­yloxy-2-hy­droxy­benzaldehyde. The mol­ecule is V-shaped and there are two intra­molecular 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 benz­yloxy ring, respectively. The latter two rings are inclined to each other by 84.4 (2)°. In the crystal, mol­ecules are linked by C—H⋯π inter­actions, forming layers lying parallel to the ab plane. The Hirshfeld surface analysis and the two-dimensional fingerprint plots confirm the predominance of these inter­actions in the crystal structure. The anti­oxidant capacity of the compound was determined by the cupric reducing anti­oxidant capacity (CUPRAC) process.
