Abstrakt: The title compound, C(7)H(9)N(3)S(2), crystallizes with two unique mol-ecules in the unit cell, both present as thio-semicarbazide tautomers. The mol-ecules differ principally in the dihedral angles between the thio-phene ring planes and the planes through the non-H atoms of the hydrazinecarbothio-amide units, viz. 9.80 (8)° for one mol-ecule and 19.37 (7)° for the other. The hydrazinecarbothio-amide units are reasonably planar, with r.m.s. deviations of 0.001Å for each of the mol-ecules. In the crystal, N-H⋯S hydrogen bonds link like mol-ecules into R(2) (2)(8) inversion dimers. A three-dimensional network structure is generated by additional N-H⋯S hydrogen bonds and weak C-H⋯S contacts between the unique mol-ecules.
