Ball-and-stick model of an (SiS₂)_∞ chain in the crystal structure of silicon sulfide, SiS₂.

This image is based on the normal, ambient-pressure orthorhombic (space group Ibam) crystal structure of SiS₂ first reported in 1935 and recently redetermined along with three high-pressure polymorphs in J. Evers, P. Mayer, L. Möckl, G. Oehlinger, Inorg. Chem. 2015, 54, 1240–1253, 10.1021/ic501825r.

Colour code:

  Silicon, Si: green-grey

  Sulfur, S: yellow
