Crystal and Molecular Structure of 3,5-Diphenyl-4,5-dihydro-2-phenylcarboxamide-1H-pyrazole

Abstract

Crystal structure of the title compound C<inf>22</inf>H<inf>19</inf>N<inf>3</inf>O is determined by single crystal X-ray diffraction (sp. gr. P2<inf>1</inf>/c, Z = 4). The molecule as a whole, is not planar: phenyl cycles are rotated relative to the plane of pyrazole ring. N−HN intramolecular hydrogen bond forms five-membered ring fused to pyrazole ring. There are also intramolecular C−HO and C−H interactions. Intermolecular C−HO hydrogen bond links the molecules into a C(7) chain along the a axis. The crystal structure is stabilized also by C–H and intermolecular hydrogen bonds. © 2017, Pleiades Publishing, Inc.
