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

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.

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

In the title compound, C21H20N2O3, the planes of the benzene ring and the naphthalene ring system are inclined to one another by 70.95°, and by 4.99 (6) and 75.93 (5)°, respectively, to the mean plane of the pyrazoline ring. The latter has an envelope conformation with the methine (CH) C atom as the flap. There is an intra-molecular O-H⋯N hydrogen bond that forms an S(6) ring motif. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming chains along [100]. The chains are linked via C-H⋯N hydrogen bonds, forming sheets parallel to the ab plane. The sheets are linked by a series of N-H⋯π and C-H⋯π inter-actions forming a three-dimensional structure.
