4-[Tris(1H-pyrazol-1-yl)meth-yl]phenol.

ABSTRACT: 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.

Crystal structure of 3-meth-oxy-2-[5-(naphthalen-1-yl)-4,5-di-hydro-1H-pyrazol-3-yl]phenol.

Project description:In the title compound, C20H18N2O2, the central pyrazoline ring has an envelope conformation with the atom substituted by the naphthalene ring as the flap. It bridges a benzene ring and a naphthalene ring system which are almost normal to one another, making a dihedral angle of 82.03 (6) °. There is an intra-molecular O-H⋯N hydrogen bond forming an S(6) ring motif. In the crystal, mol-ecules are linked by pairs of N-H⋯π inter-actions, forming inversion dimers. There are also C-H⋯π inter-actions present and the dimers are linked via C-H⋯O hydrogen bonds, forming ribbons propagating along the a-axis direction.
