5-(Biphenyl-4-yl)-3-(4-tert-butylphenyl)-1H-pyrazole

Abstract

Key indicators: single-crystal X-ray study; T = 292 K; mean (C-C) = 0.004 Å; R factor = 0.060; wR factor = 0.184; data-to-parameter ratio = 14.3.The molecules of the title compound, C 25 H 24 N 2 , are connected by intermolecular N-HÁ Á ÁN hydrogen bonds to form dimers. The crystal packing is stabilized by van der Waals forces. Related literatureFor related literature, see: Aggarwal et al. (2003); Claramunt et al. (2006); Hayter et al.
