Two dimorphs of 5-methylsulfanyl-1H-tetrazole.
5-Methylsulfanyl-1H-tetrazole, C(2)H(4)N(4)S, crystallizes in dimorphic forms; the alpha-form crystallizes at room temperature in the monoclinic crystal system, space group P2(1)/m, and the beta-form crystallizes by sublimation at 423 K in the orthorhombic crystal system, space group Pbcm. In both forms, the molecules occupy crystallographic mirror planes and are connected to one another via N-H...N hydrogen bonds, the amino H atoms being disordered. The two forms differ from one another in their packing; there are polar layers in the alpha-form and non-polar layers in the beta-form.
