Abstract

Crystallography Physical Sciences Science & Technology
The five-membered dihydropyrazole ring in the title compound, C10H9F3N2O, is approximately planar (r.m.s. deviation 0.111 angstrom for all non-H atoms) and its phenyl substituent is aligned at an angle of 14.7 (2)degrees. Adjacent molecules are linked by N-H center dot center dot center dot O and O-H center dot center dot center dot N hydrogen bonds, generating ribbons running along the b axis of the monoclinic unit cell.
