چکیده
The title compound, C(12)H(11)N(4)OS(2), has been synthesized by the condensation reaction of 3-oxo-2-(phenyl-hydrazono)butanate and S-methyl-dithio-carbazate. The hydrazine unit and the pyrazole ring are coplanar [dihedral angle 3.8 (4)°] due to extensive conjugation and the N-H⋯O=C intra-molecular hydrogen bond. Two adjacent mol-ecules form dimers due to short C-H⋯O=C [R(2) (2) (18)] and C-H⋯S=C [R(2) (2) (22)] inter-molecular inter-actions. C-H⋯S-C [R(2) (2) (14)] inter-actions link these dimers into ribbons in the [011] direction.
