title: 2-Isonicotinoyl-N-phenyl-hydrazine-carbothio-amide dimethyl-formamide hemisolvate.
abstract: The title compound, C(13)H(12)N(4)OS·0.5C(3)H(7)NO, contains four hydrazine mol-ecules and two solvent mol-ecules in the asymmetric unit. The dihedral angles between the pyridine and phenyl rings in the hydrazine mol-ecules are 67.51 (16), 68.28 (16), 81.36 (15) and 83.32 (15)°. In the crystal, the mol-ecules are linked by N-H⋯N, N-H⋯O and N-H⋯S hydrogen bonds.
