✦ Synopsis
The title compound, C 16 H 6 Br 2 Cl 2 N 2 S 2 , was synthesized from the reaction of equimolar amounts of 1,2-diamino-4,5dichlorobenzene and 1,2-bis(5-bromothien-2yl)ethanedione. The crystal structure was determined at 100 K.

The crystal structure of the title compound, C 23 H 28 Br 4 O 6 , confirms that it consists of two hexasubstituted aromatic units linked by a central methylene group. The molecule lies on a crystallographic twofold axis that passes through the methylene bridging atom. Examination of the extended str
The title compound, C~18~H~13~BrO~2~S, is chiral due to the twist of the naphthalene and thienyl rings about the chalcone backbone [dihedral angle = 17.75 (10)°]. There are weak C—H...O interactions which link the molecules into chains in the __b__ direction.
