【 摘 要 】

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 intra­molecular O—H⋯N hydrogen bond forming an S(6) ring motif. In the crystal, mol­ecules are linked by pairs of N—H⋯π inter­actions, forming inversion dimers. There are also C—H⋯π inter­actions present and the dimers are linked via C—H⋯O hydrogen bonds, forming ribbons propagating along the a-axis direction.
