4-Nitro­phthalo­nitrile

摘要

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.
