چکیده
The nine-membered fused-ring system of the title pyridazine derivative, C(7)H(7)N(3)OS, is almost planar (r.m.s. deviation 0.012 Å). In the crystal, the amino H atom forms a hydrogen bond to the ketonic O atom of a neighboring mol-ecule to generate a centrosymmetric dimer.

The thia-zole-pyridazine fused-ring system of the title compound, C(13)H(12)N(4)O(3)S(2), is approximately planar (r.m.s. deviation = 0.037 Å); the benzene ring connected to the fused-ring system through the N atom is twisted by 39.3 (1)°. The amine group uses an H atom to form a hydrogen bond to the ketonic O atom of an inversion-related mol-ecule to generate a dimer; adjacent dimers are linke...

In the structure of the title compound, C(7)H(10)OS(4)Si, the carbonyl O atom lies in the plane of the five-membered dithiole ring with a deviation of only 0.022 (2) Å. The seven-membered ring adopts a chair conformation. The crystal packing is stabilized by S⋯O [3.096 (4) Å] and S⋯S [3.620 (4) Å] contacts, together with C-H⋯S inter-actions.
