Silicon sulfide refers to the chemical compound with the formula SiS2. This material is polymeric and adopts a structure quite different from the corresponding silicon dioxide polymorphs. The material consists of chains of edge-shared tetrahedra, Si(μ-S)2Si(μS)2 etc. The Si---Si distances at 214 picometers are shorter than conventional Si-Si single bonds. [Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001. ISBN 0-12-352651-5.]

The material is formed by heating silicon and sulfur or by the exchange reaction between SiO2 and Al2S3. Like all silicon sulfur-compounds, SiS2 hydrolyzes readily to release H2S and form hydrated silica gel.
