Abstract

Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.004 Å; R factor = 0.054; wR factor = 0.181; data-to-parameter ratio = 10.1.In the title compound, C 16 H 8 F 6 N 2 , the dihedral angle between the pyrazole and difluorobenzene rings is 50.30 (13) , while those between the pyrazole and fluorobenzene rings and between the difluorobenzene and fluorobenzene rings are 38.56 (13) and 53.50 (11) , respectively. Aromaticstacking interactions between adjacent difluorobenzene rings [centroid-centroid separation = 3.6082 (11) Å ] link the molecules into dimers parallel to [212]. Related literature
