Chemical chemical compound

Tin(IV) sulfide is a compound with the formula SnS
_two . The compound crystallizes in the cadmium iodide motif, with the Sn(IV) situated in "octahedral holes' divers past 6 sulfide centers.^[5] Information technology occurs naturally equally the rare mineral berndtite.^[6] It is useful as semiconductor material with band gap 2.2 eV.^[7]

Reactions [edit]

The compound precipitates as a brown solid upon the addition of H
₂ S to solutions of tin(IV) species. This reaction is reversed at low pH. Crystalline SnS
₂ has a bronze colour and is used in decorative blanket^[8] where it is known as mosaic gold.

The material also reacts with sulfide salts to give a series of thiostannates with the formula [SnS
₂ ]
_m [S] ^{iidue north−}
_n . A simplified equation for this depolymerization reaction is

SnS
₂ + S ²⁻
→ 1 ten [SnS ²⁻
_three ]
_ten .
