Abstract
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 [Formula presented] ring motifs. Weak C—H⋯O interactions link the molecules, forming layers parallel to the [Formula presented] 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).
