摘要：

In the title compound, C17H12N4O6, the dinitrophenyl and 2-hydroxy-5-methylphenyl groups are oriented with dihedral angles of 23.9 (1) and 13.1 (1)degrees, respectively, with respect to the pyrazole ring. The internal C-C-C ring angles at the ortho and para positions where NO2 is bonded are 121.7 (2) and 121.9 (2)degrees. The dihedral angle between the phenyl rings is 11.2 (1)degrees. The crystal structure is stabilized by O-H . . .N intramolecular and by C-H . . .O intermolecular hydrogen bonds.
