چکیده
In the title mol-ecule, C9H10N2S, one of the methyl groups is almost co-planar with the thia-zolo-pyridine rings with a deviation of 0.311 (3) Å from the least-squares plane of the thia-zolo-pyridine group. In the crystal, weak C-H⋯N hydrogen-bonding inter-actions lead to the formation of chains along [011].

In the title compound, C12H14N2S, the cyclo-hexane ring adopts a chair conformation with the exocyclic C-C bond in an equatorial orientation. The mean plane through the cyclo-hexane ring (all atoms) is twisted from the thia-zolo-pyridine ring system (r.m.s. deviation = 0.013 Å) by 39.57 (6)°. In the crystal, mol-ecules form (100) sheets, although there are no specific directional inter-actions ...
