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] ReactionsThe compound precipitates as a brown solid upon the addition of {{chem|H|2|S}} to solutions of tin(IV) species. This reaction is reversed at low pH. Crystalline {{chem|SnS|2}} has a bronze color and is used in decorative coating[8] where it is known as mosaic gold. The material also reacts with sulfide salts to give a series of thiostannates with the formula {{chem|[SnS|2|]|m|[S]|n|2n−}}. A simplified equation for this depolymerization reaction is {{chem|SnS|2}} + {{chem|S|2-}} → {{sfrac|1|x}}{{chem|[SnS|3|2-|]|x}}.
