(E)-3-[(Dimethylamino)methylidene]-4-phenyl-1H-1,5-benzodiazepin-2(3H)-one
Abstract
The asymmetric unit of the title compound, C18H17N3O, consists of two independent molecules, each having an E conformation with respect to the C=C bond between the benzodiazepinone and dimethylamine groups. In the crystal, the two independent molecules are linked into a dimer by a pair of N—H...O hydrogen bonds.
