(2 Z )‐2‐Bromo‐3‐[3,5‐dibromo‐4‐(ethylamino)phenyl]‐1‐(2,4‐dichlorophenyl)prop‐2‐en‐1‐one

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.
