3-(4-Chloro-phen-yl)-5-(thio-phen-2-yl)-4,5-dihydro-1H-pyrazole-1-carbothio-amide.

ABSTRACT: In the title pyrazoline derivative, C(14)H(12)ClN(3)S(2), the thiophene ring is disordered over two orientations with a refined site-occupancy ratio of 0.832 (4):0.168 (4). The pyrazoline ring adopts an envelope conformation with the C atom linking the thiophene ring at the flap. The dihedral angles between the benzene ring and the major and minor components of the thiophene ring are 88.6 (3) and 85.6 (15)°, respectively while the dihedral angle between the disorder components of the ring is 3.1 (16)°. The mean plane of the pyrazoline ring makes dihedral angles of 11.86 (13), 80.1 (3) and 83.0 (15)°, respectively, with the benzene ring, and the major and minor components of the thiophene ring. An intra-molecular N(amide)-H⋯N(pyrazoline) hydrogen bond generates an S(5) ring motif. In the crystal, mol-ecules are linked by weak C-H⋯S and N(amide)-H⋯S inter-actions into a tape along [10[Formula: see text]]. C-H⋯π inter-actions are also observed.
