6,6′-Dimethoxy-2,2′-[(E,E′)-(4-chloro-m-phenylene)bis(nitrilomethylidyne)]diphenol

Abstract

The title compound, C22H19ClN2O4, has the appearance of a warped butterfly. One 2-hydroxy-3-methoxybenzylideneamino fragment is planar [with a maximum deviation of 0.056 (3) Å] and forms a dihedral angle of 9.85 (9)° with the central benzene ring. The other fragment is not planar; however, the methoxyphenol group is planar [with the maximum deviation of 0.033 (2) Å] and makes a dihedral angle of 41.7 (3)° with the central benzene ring. The molecule is stabilized by intramolecular O—H...N hydrogen bonding. The crystal structure is stabilized by weak intermolecular C—H...O hydrogen bonding and C—H...π interactions.
