2-{5-[2-(4-Nitrophenoxy)phenyl]-1-phenyl-1H-pyrazol-3-yl}phenol

Abstract

In the title compound, C27H19N3O4, the phenol and pyrazole rings are almost coplanar [dihedral angle = 0.95 (12)°] due to an intramolecular O—H...N hydrogen bond, whereas the phenyl ring is tilted by 40.81 (7)° with respect to the plane of the pyrazole ring. The aromatic ring with a nitrophenoxy substituent makes a dihedral angle of 54.10 (7)° with the pyrazole ring.
