2,7-Dimethyl-1,3-thia-zolo[4,5-d]pyridazin-4(5H)-one.


ABSTRACT: 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.
