Tin(II) sulfide is a chemical compound of tin and sulfur. The chemical formula is SnS. Its natural occurrence concerns herzenbergite, a rare mineral.
Synthesis
Tin(II) sulfide can be prepared by reacting tin with sulfur, or tin(II) chloride with hydrogen sulfide.
- Sn + S → SnS
- SnCl2 + H2S → SnS + 2HCl
Properties
Tin(II) sulfide is a brown solid, insoluble in water, but soluble in concentrated hydrochloric acid. Tin (II) sulfide is soluble in (NH4)2S. It has a layer structure similar to that of black phosphorus.[3] As per black phosphorus, tin(II) sulfide can be ultrasonically exfoliated in liquids to produce atomically thin semiconducting SnS sheets that have a wider optical band gap (>1.5 eV) compared to the bulk crystal.[4]
