Crystal Structure of 1-acetyl-3-(4-methylphenyl)-5-phenyl-4,5-dihydro-1H-pyrazole

Abstract

In the title compound, C<inf>18</inf>H<inf>18</inf>N<inf>2</inf>O, the whole molecule is not planar but the phenyl ring systems are planar individually. The central pyrazole ring system is twisted with puckering parameters Q = 0.1610(18) Å and φ = 82.2(6)°. The crystallographic structure is stabilized by C-H⋯N type intramolecular hydrogen bond, generating ring motif R(5). © 2014, Pleiades Publishing, Inc.
