7-[4-(4-Fluorophenyl)-2-methylsulfanyl-1H-imidazol-5-yl]tetrazolo[1,5-a]-pyridine

The crystal structure of the title compound, C15H11FN6S, forms a three-dimensional network stabilized by pi-pi interactions between the imidazole core and the tetrazole ring of the tetrazolopyridineunit; the centroid-centroid distance is 3.627 (1) angstrom. The crystal structure also displays bifurcated N-H center dot center dot center dot(N,N) hydrogen bonding and C-H center dot center dot center dot F interactions. The former involve the NH H atom of the imidazole core and the tetrazolopyridine N atoms, while the latter involve a methyl H atom, of the methylsulfanyl group, and the 4-fluorophenyl F atom. In the molecule, the imidazole ring makes dihedral angles of 40.45 (9) and 17.09 (8)degrees, respectively, with the 4-fluorophenyl ring and the tetrazolopyridine ring mean plane.
