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]
