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]
The compound precipitates as a brown solid upon the addition of H
2S to solutions of tin(IV) species. This reaction is reversed at low
pH. Crystalline 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 [SnS
2
m[S]2n−
n. A simplified equation for this depolymerization reaction is
Tin (IV) sulfide has various uses in electrochemistry. It can be used in anodes of lithium-ion batteries, where an intercalation process occurs to form Li2S. [9] It can also be used in a similar way in electrodes of supercapacitors, which can be used as alternative source of energy storage. [10]
SnS2 has also been identified as a potential component of thermoelectric devices, which convert thermal energy to electrical energy. In one example, this property was made possible by forming a composite of SnS2 with multiwalled carbon nanotubes. [11]
SnS2 can also be used in wastewater treatment. Forming a membrane with SnS2 and carbon nanofibers can potentially allow for the reduction of certain impurities in water, an example of which is hexavalent chromium. [12]
In general, SnS2 is useful as a semiconductor and can be purchased in powder form for experimental purposes. [13]
