An orthorhombic polymorph of 3,5-bis[4-(dimethylamino)benzylidene]-1-methyl-4-piperidone

The title compound, C24H29N3O, is an orthorhombic modification of the known monoclinic polymorph. In the crystal structure, weak C—H⋯N and C—H⋯O hydrogen bonds help to establish a non-centrosymmetric packing arrangement.
