1,3-Bis{(E)-[4-(dimethylamino)benzylidene]amino}propan-2-ol: chain structure formation via an O—H...N hydrogen bond

  • The asymmetric unit of the title compound, C21H28N4O, consists of two unique mol­ecules linked by an O—H⋯N hydrogen bond. The conformation of both C=N bonds is E and the azomethine functional groups lie close to the plane of their associated benzene rings in each of the independent mol­ecules. The dihedral angles between the two benzene rings are 83.14 (4) and 75.45 (4)°. The plane of the one of the N(CH3)2 units is twisted away from the benzene ring by 18.8 (2)°, indicating loss of conjugation between the lone electron pair and the benzene ring. In the crystal structure, O—H⋯N hydrogen bonds together with C—H⋯O hydrogen bonds link neighbouring supra­molecular dimers into a three-dimensional network.
