The crystal structure of the title compound, C(15)H(11)FN(6)S, forms a three-dimensional network stabilized by π-π inter-actions between the imidazole core and the tetra-zole ring of the tetra-zolopyridine-unit; the centroid-centroid distance is 3.627 (1) Å. The crystal structure also displays bifurcated N-H⋯(N,N) hydrogen bonding and C-H⋯F inter-actions. The former involve the NH H atom of the imidazole core and the tetra-zolopyridine N atoms, while the latter involve a methyl H atom, of the methyl-sulfanyl group, and the 4-fluoro-phenyl F atom. In the mol-ecule, the imidazole ring makes dihedral angles of 40.45 (9) and 17.09 (8)°, respectively, with the 4-fluoro-phenyl ring and the tetra-zolopyridine ring mean plane.
