2-{5-[2-(4-Nitro-phen-oxy)phen-yl]-1-phenyl-1H-pyrazol-3-yl}phenol.


ABSTRACT: In the title compound, C(27)H(19)N(3)O(4), the phenol and pyrazole rings are almost coplanar [dihedral angle = 0.95?(12)°] due to an intra-molecular 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 nitro-phen-oxy substituent makes a dihedral angle of 54.10?(7)° with the pyrazole ring.

In the title compound, C(27)H(19)N(3)O(4), the phenol and pyrazole rings are almost coplanar [dihedral angle = 0.95 (12)°] due to an intra-molecular 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 nitro-phen-oxy substituent makes a dihedral angle of 54.10 (7)° with the pyrazole ring. ...[more]
