Abstract
In the title compound, the central pyrazole ring adopts a twisted conformation on the –CH—CH2– bond and its mean plane makes dihedral angles of 7.19 (12) and 71.13 (11)° with the attached thiophene and toluene rings, respectively. In the crystal, molecules are linked by N—H⋯S hydrogen bonds, forming chains propagating along [010].
In the title compound, C15H15N3S2, the central pyrazole ring adopts a twisted conformation on the –CH—CH2– bond. Its mean plane makes dihedral angles of 7.19 (12) and 71.13 (11)° with those of the thiophene and toluene rings, respectively. The carbothiamide group [C(=S)—N] is inclined to the pyrazole ring mean plane by 16.8 (2)°. In the crystal, molecules are linked by N—H⋯S hydrogen bonds, forming chains propagating along [010]. Within the chains, there are N—H⋯π interactions present. Between the chains there are weak parallel slipped π–π interactions involving inversion-related thiophene and pyrazole rings [inter-centroid distance = 3.7516 (14) Å; inter-planar distance = 3.5987 (10) Å; slippage = 1.06 Å].
