Özet

The title compound, C21H17N7O4, is in an 'extended' conformation aided by an intramolecular N-H center dot center dot center dot O hydrogen bond. The pyrazole ring makes dihedral angles of 29.17 (6), w65.47 (4) and 9.91 (7)degrees, respectively, with the phenyl, pyrrole and benzene rings. In the crystal, molecules are connected by pairs of N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds, forming inversion dimers which associate into ribbons running along the b axis through complementary C-H center dot center dot center dot O interactions.
