3-Phenyl-5-(2-Thienyl)-2-Pyrazoline-1-Thioamide

Abstract

In the crystal structure of the title compound, C<inf>14</inf>H <inf>13</inf>N<inf>3</inf>S<inf>2</inf>, the planar phenyl and thiophene rings are bridged by a pyrazoline ring. The phenyl group is almost perpendicular to the pyrazoline ring. The pyrazoline ring adopts an envelope conformation, and the two N atoms are involved in an intramolecular N-H⋯N(pyrazoline) and an intermolecular N-H⋯S hydrogen bond. The average C-N bond length is 1.385 (4) Å. The crystal structure is stabilized by intra- and intermolecular hydrogen bonds and C-H⋯π stacking interactions. © 2006 International Union of Crystallography Printed in Great Britain - all rights reserved.
