Özet

The title compound, C12H7N3O2, is a 1-nitro derivative of the ligand benzo[c]cinnoline. The rings in the benzo[c]cinnoline skeleton are close to planarity, while the skeleton itself is non-planar. The dihedral angles between the rings in the benzo[c]cinnoline skeleton are alpha<^>beta 4.0(5), alpha<^>gamma 8.4(2) and beta<^>gamma 4.5(4)degrees; in benzo[c]cinnoline the alpha<^>gamma dihedral angle is 2.5 degrees. The difference is caused by steric interactions between the nitro group and benzo[c]cinnoline skeleton.
