6,6'-Dimeth-oxy-2,2'-[(E,E')-(4-chloro-m-phenyl-ene)bis-(nitrilo-methyl-idyne)]diphenol

The title compound, C(22)H(19)ClN(2)O(4), has the appearance of a warped butterfly. One 2-hydr-oxy-3-methoxy-benzyl-idene-amino 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 methoxy-phenol 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 mol-ecule is stabilized by intra-molecular O-H⋯N hydrogen bonding. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonding and C-H⋯π inter-actions.
