In the title compound, C10H8N4O3·C3H7NO, the asymmetric unit contains two crystallographically independent molecules A and B, each of which has one DMF solvate molecule. Molecules A and B both feature intramolecular N--H...O hydrogen bonds, forming S(6) ring motifs and consolidating the molecular configuration. In the crystal, N--H...O and O--H...O hydrogen bonds connect molecules A and B, forming R²2(8) ring motifs. Weak C--H...O interactions link the molecules, forming layers parallel to the (212) plane. The DMF solvent molecules are also connected to the main molecules (A and B) by N--H...O hydrogen bonds. π-π stacking interactions [centroid-to-centroid distance = 3.8702(17)Å] between the layers also increase the stability of the molecular structure in the third dimension. According to the Hirshfeld surface study, O...H/H...O interactions are the most significant contributors to the crystal packing (27.5% for molecule A and 25.1% for molecule B).
