Abstract

The title compound, C16H14N6O, was prepared by the condensation of 4-(trifluoromethyl) phenol and sodium pyrazol-1-ide in a yield of 58%. The dihedral angles formed by the planes of the pyrazole rings are 50.7 (2), 71.2 (3) and 95.8 (2)degrees. The molecules are associated into dimers by pairs of intermolecular O-H center dot center dot center dot N hydrogen bonds involving the hydroxy groups and pyrazole N atoms. In addition, pi-pi stacking between the phenol rings of these inversion-related dimers is observed, with a ring centroid-to-centroid distance of 3.9247 (10) angstrom.
