Abstract

In the title compound, C25H26N2O4·CHCl3, the aromatic rings of the imino­methyl-6-meth­oxy­phenol fragments make dihedral angles of 58.33 (6) and 87.74 (6)° with the central benzene ring. The mol­ecular conformation is stabilized by intra­molecular O—H⋯N hydrogen bonds. In the crystal, an inter­molecular C—H⋯O hydrogen bond involving the chloro­form solvent mol­ecule is observed. The crystal packing is further stabilized by π–π stacking inter­actions [centroid–centroid distances = 3.739 (3)–3.776 (3) Å] between the benzene rings of centrosymmetrically related mol­ecules.
