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


ABSTRACT: 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?? and C-H?? inter-actions forming a three-dimensional structure.
