3-phenyl-5-(2-thienyl)-2-pyrazoline-1-thioamide

Abstract

In the crystal structure of the title compound, C14H13N3S2, 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 center dot center dot center dot N( pyrazoline) and an intermolecular N-H center dot center dot center dot S hydrogen bond. The average C-N bond length is 1.385 (4) angstrom. The crystal structure is stabilized by intra- and intermolecular hydrogen bonds and C-H center dot center dot center dot pi stacking interactions.
