Abstract

In the title compound, C12H7N3O2S, the dihedral angle between the planes of the thia-zolo-pyridine ring system (r.m.s. deviation = 0.005 Å) and the benzene ring is 3.94 (6)°. The nitro group is rotated by 7.6 (2)° from its attached ring. In the crystal, extensive aromatic π-π stacking [shortest centroid-centroid separation = 3.5295 (9) Å] links the mol-ecules into (001) sheets.

Keywords: crystal structure; nitrophenyl; thiazolo[4,5-b]pyridine; thiazolopyridine derivatives.
