5-Bromobenzene-1,3-dicarbonitrile

Abstract

The asymmetric unit of the title compound, C8H3BrN2, consists of two molecules. The crystal structure features undulating molecular sheets with the molecules linked by C—H...N hydrogen bonds with one N atom acting as a bifurcated acceptor. N...Br interactions also occur [N...Br = 2.991 (3) and 3.099 (3) Å]. Interlayer association is accomplished by offset face-to-face arene interactions [centroid–centroid distance = 3.768 (4) Å].
