چکیده
In the crystal structure of the title compound, C22H13Br2N3, the two bromo-phenyl rings are rotated out of the plane of the central benzyl-idene 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 mol-ecules are linked by weak C-H⋯N hydrogen bonds into layers parallel to the bc plane.
