Abstract
The asymmetric unit of the title compound, C6H5Cl2N·2C11H11Cl2NO, is composed of one molecule of an enamino–ketone [i.e. –(2,6-dichlorophenylamino)pent-3-en-2-one] and half a molecule of 2,6-dichloroaniline, the whole molecule of the latter component being generated by twofold rotational symmetry. In this latter molecule, there are two intramolecular N—H⋯Cl contacts. In the enamino–ketone molecule, there is an N—H⋯O hydrogen bond of moderate strength, and the dihedral angle between the benzene ring and pentanone fragment [C—C(—N)=C—C(=O)—C; planar within 0.005 (1) Å] is 81.85 (7)°. In the crystal, two molecules of the enamino–ketone are bridged by a molecule of 2,6-dichloroaniline via N—H⋯O hydrogen bonds of moderate strength. There are also π–π interactions present, involving the benzene rings of inversion-related enamino–ketone molecules [centroid–centroid distance = 3.724 (4) Å].
