organic compounds
The non-H atoms of the title compound, C8H10N2O2, are almost coplanar. The conformation is stabilized by an intramolecular N—HO hydrogen bond. The molecules are linked via intermolecular N—HO hydrogen bonds into a one-dimensional chain. There are intermolecular C—Hπ interactions and ππ stacking interactions present in the structure. The hydrogen-bonded chain is expanded into a three-dimensional net via stacking interactions.
