(E)-{4-Amino-3-[4-(dimethylamino)benzylideneamino]phenyl}(phenyl)methanone

Abstract

The title compound, C22H21N3O, crystallizes with two independent mol­ecules in the asymmetric unit. The bond lengths and angles in both mol­ecules are within normal ranges. The dihedral angles between benzene rings within the mol­ecule are 32.4 (3) and 52.6 (3)° between the central and outer rings and 80.6 (3)° between the outer rings. The dihedral angles between benzene rings within the second molecule are 42.7 (3) and 57.0 (1)° between the central and outer rings and 82.8 (8)° between the outer ring. The crystal packing is stabilised by N—H⋯O hydrogen bonds linking the mol­ecules into layers.
