3,3′-Dimeth­­oxy-2,2′-[(4,5-di­methyl-o-phenyl­ene)bis­­(nitrilo­methanylyl­­idene)]diphenol.

The asymmetric unit of the title compound, C24H24N2O4, comprises two crystallographically independent mol­ecules A and B. The dihedral angles between the central dimethyl-substituted benzene ring and the two outer benzene rings are 49.5 (1) and 5.06 (11)° in mol­ecule A, and 42.55 (8) and 5.77 (9)° in mol­ecule B. In each mol­ecule, two strong intra­molecular O—H⋯N hydrogen bonds generate two S(6) ring motifs. The crystal structure is further stabilized by inter­molecular π–π [centroid–centroid distances of 3.591 (1)–3.876 (1) Å] inter­actions
