title: Methyl 3-(pyridin-4-yl-methyl-idene)di-thio-carbazate.
abstract: There are two independent mol-ecules in the asymmetric unit of the title mol-ecule, C8H9N3S2, both of which exhibit an E conformation with the pyridine ring and di-thio-carbazate fragment located on opposite sides of the C=N bond. The pyridine ring and di-thio-carbazate group are approximately coplanar, with dihedral angles of 4.74 (1) and 8.77 (1)° between their planes in the two mol-ecules. In the crystal, mol-ecules are linked to each other via N-H⋯N hydrogen bonds, forming zigzag chains parallel to [10-1].
