Abstract:
The title compound, C15H16N4S, exists in the Z conformation
with the thionyl S atom lying cis to the azomethine N atom.
The shortening of the N—N distance [1.3697 (17) A ° ] is due to
extensive delocalization with the pyridine ring. The hydrazine–
carbothioamide unit is almost planar, with a maximum
deviation of 0.013 (2) A ° for the amide N atom. The stability of
this conformation is favoured by the formation of an
intramolecular N—H N hydrogen bond. The packing of
the molecules involves no classical intermolecular hydrogenbonding
interactions; however, a C—H interaction occurs
