(Z)-1-(1,3-Diphenyl-1H-pyrazol-4-yl)-N-phenylmethanimine N-oxide

Abstract

In the title nitrone, C22H17N3O, the dihedral angles between the central pyrazole ring and pendant N-bound, C-bound and nitrone-bound phenyl rings are 20.93 (6), 41.27 (6), and 32.57 (6)°, respectively. In the crystal, (101) layers are generated by C—H...O hydrogen bonds coupled with C—H...π(ring) and offset π–π stacking interactions.
