Tin(IV) sulfide is a compound with the formula Sn S
₂. The compound crystallizes in the cadmium iodide motif, with the Sn(IV) situated in "octahedral holes' defined by six sulfide centers.^[5] It occurs naturally as the rare mineral berndtite.^[6] It is useful as semiconductor material with band gap 2.2 eV.^[7]
