4-[Tris(1H-pyrazol-1-yl)meth-yl]phenol.
The title compound, C(16)H(14)N(6)O, was prepared by the condensation of 4-(trifluoro-meth-yl)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)°. The mol-ecules are associated into dimers by pairs of inter-molecular O-H⋯N hydrogen bonds involving the hy-droxy groups and pyrazole N atoms. In addition, π-π stacking between the phenol rings of these inversion-related dimers is observed, with a ring centroid-to-centroid distance of 3.9247 (10) Å.
