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[edit]

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[edit]

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]
