Abstract: The molecule of the title compound, C₂₁H₁₇N₅O₈·C₃H₇NO, is non-planar. The central benzene ring makes dihedral angles of 86.87 (8) and 4.52 (6)° with the terminal benzene ring bonded to the ethoxy functionality and the p-nitrophenyl residue bonded to the hydrazine functionality, respectively. Intramolecular N-HO and C-HO hydrogen bonds help to stabilize the molecular conformation, while weak intermolecular C-HO hydrogen bonds link adjacent molecules to form infinite chains in the crystal structure.
