✦ Synopsis

In the title compound, C~17~H~12~Br~3~Cl~2~NO, the mean planes of the 3,5-dibromo-4-phenyl and 2,4-dichlorophenyl groups make a dihedral angle of 72.4 (2)°. The dihedral angles between the 2-bromoprop-2-en-1-one group and the two phenyl ring groups (3,5-dibromo-4-phenyl and 2,4-dichlorophenyl) are 71.1 (1) and 10.9 (4)°, respectively. The crystal packing is stabilized by intermolecular N—H...O hydrogen-bond interactions between the ethylamino H atom and the propyl ketone O atom, with the 3,5-dibromo-4-phenyl rings linked in chains in an alternate inverted pattern parallel and oblique to the ac face and diagonally along the a axis of the unit cell. An intramolecular hydrogen bond between the ethyl amino H atom and the 5-Br atom from the 3,5-dibromo-4-phenyl group helps stabilize the molecular conformation.
