4,4′-Dimethyl-2,2′-[1,2-phenylenebis(nitrilomethylidyne)]diphenol

Abstract

In the title Schiff base, C22H20N2O2, the benzene ring forms dihedral angles of 53.92 (1) and 3.62 (1)° with the two salicylaldimine groups. There are two strong O—H...N intramolecular hydrogen bonds. The crystal packing is stabilized by weak intermolecular C—H...O hydrogen bonds and π–π stacking interactions (average distance 3.39 Å).
