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⋯N(pyrazoline) and an inter­molecular N—H⋯S hydrogen bond. The average C—N bond length is 1.385 (4) A. The crystal structure is stabilized by intra- and inter­molecular hydrogen bonds and C—H⋯π stacking inter­actions.
