title: Pyridine-2-carbaldehyde thio-semi-carbazone.
abstract: The asymmetric unit of the title compound, C(7)H(8)N(4)S, contains two independent mol-ecules with slightly different conformations; the dihedral angles between the pyridine ring and mean plane of the thio-semicarbazone unit in the two mol-ecules are 2.88 (5) and 6.30 (5)°. Inter-molecular N-H⋯N and N-H⋯S hydrogen bonds link the mol-ecules into layers parallel to the ab plane.
