2-Sulfanylidene-1,2-dihydropyridine-3-carbohydrazide

چکیده
All non-H atoms of the title compound, C(6)H(7)N(3)OS, which exists in the thione form, lie in a common plane (r.m.s. of non-H atoms = 0.08 Å). The amino group of the -NH-NH(2) substituent forms an intra-molecular hydrogen bond to the S atom. The terminal -NH(2) group is pyramidally coordinated; it forms a weak N-H⋯O and a weak N-H⋯S hydrogen bond. Furthermore, the N atom is an acceptor for a C-H⋯N contact. The amino group of the ring is a hydrogen-bond donor to the carbonyl O atom of an adjacent mol-ecule, this inter-action giving rise to a linear chain motif running along the b axis.

The six-membered heterocycle in the title compound, C(18)H(16)BrN(3)O(4)S, adopts a sofa conformation. Intra-molecular N-H⋯N and O-H⋯O hydrogen bonds stabilize the mol-ecular conformation by forming a five- and a six-membered ring, respectively. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds.
