title: Crystal structure of 2-(2-methyl-phen-yl)-1,3-thia-zolo[4,5-b]pyridine.
abstract: In the title mol-ecule, C13H10N2S, the dihedral angle between the planes through the non-H atoms of the methylbenzene and thi-azo-lopyridine groups is 36.61 (5)°. In the crystal, the thi-azo-lopyridine groups of inversion-related mol-ecules overlap, with a minimum ring-centroid separation of 3.6721 (9) Å. Furthermore, the methylbenzene groups from neighbouring mol-ecules inter-act edge-to-face at an angle of 71.66 (5)°. In addition, weak C-H⋯ N hydrogen bonds form chains exending along [100].
