2,6-Dibromo-4-nitrobenzonitrile

Abstract

Molecules of the title compound, C7H2Br2N2O2, haveC2vsymmetry and each lie on a twofold axis that bisects the benzene ring and its nitro and cyano substituents. The cyano N atom is bisected by two CN...Br contacts, and the nitro O atoms participate in weak C—H...O hydrogen bonds. These interactions form a planar sheet structure that stacks about a glide plane. This stacking mode has not been previously reported with cyano-halo-derived sheets of this type.
