Abstract
In the crystal structure of the title compound, C22H13Br2N3, the two bromophenyl rings are rotated out of the plane of the central benzylidene ring by 68.7 (1) and 69.3 (1)°. Both cyano substituents are located nearly in the plane of the benzylidene ring, with the mean plane of the methylmalononitrile group being inclined to this ring by 5.8 (1)°. In the crystal, the molecules are linked by weak C—H⋯N hydrogen bonds into layers parallel to the bc plane.
