4-Nitrophthalonitrile
Abstract
In the title compound, C8H3N3O2 (systematic name: 4-nitrobenzene-1,2-dicarbonitrile), the nitro group is twisted out of the plane of the benzene ring to which it is attached [O—N—Cring—Cring torsion angle = 9.80 (13)°]. In the crystal packing, supramolecular layers with a zigzag topology in the ac plane are sustained by C—H...N interactions.
