Abstract: | Molecules of the title compound, C12H10N2O2, are markedly non‐planar. There is an intramolecular N—H?O hydrogen bond, and the molecules are linked into zigzag chains by a single C—H?O hydrogen bond. Comparisons are made with the supramolecular aggregation in isomeric amino–nitro derivatives, and in some N‐methylnitroanilines. |
