Abstract

Crystallography Physical Sciences Science & Technology
In the title compound, C19H18N4O3, the pyrazole ring is oriented at dihedral angles of 41.12 (7) and 12.25 (10)degrees, respectively, with respect to the planes of the phenyl and benzene rings. Intramolecular N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds generate seven-and six-membered S(7) and S(6) ring motifs, respectively.
