Two dimorphs of 5-methylsulfanyl-1H-tetrazole

N. Fridman, M. Kapon and M. Kaftory

Abstract: 5-Methylsulfanyl-1H-tetrazole, C₂H₄N₄S, crystallizes in dimorphic forms; the [alpha] -form crystallizes at room temperature in the monoclinic crystal system, space group P2₁/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-HN 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.

Formula: Two dimorphs of C₂H₄N₄S
