title: 3-Methyl-5-oxo-4-(2-phenyl-hydrazinyl-idene)-4,5-dihydro-1H-pyrazole-1-carbothio-amide.
abstract: In the title compound, C(11)H(11)N(5)OS, the pyrazole ring is approximately planar, with a maximum deviation of 0.010 (2) Å. The dihedral angles between the benzene ring and the pyrazole and carbothio-amide groups are 5.42 (9) and 10.61 (18)°, respectively. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are connected by inter-molecular N-H⋯O and C-H⋯S hydrogen bonds, forming R(2) (2)(12) ring motifs. In addition, there is a π-π stacking inter-action [centroid-centroid distance = 3.5188 (11) Å] between the pyrazole and benzene rings. These inter-actions link the mol-ecules into infinite chains along [001].
