Chemical compound

Silicon monosulfide is achemical compound ofsilicon andsulfur. Thechemical formula is SiS. Molecular SiS has been detected at high temperature in the gas phase.^[1] The gas phase molecule has an Si-S bondlength of 192.93 pm, this compares to the normal single bond length of 216 pm,^[1]^[2] and is shorter than the Si=S bond length of around 201 pm reported in an organosilanethione.^[1] Historically a pale yellow-red amorphous solid compound has been reported.^[3] The behavior of silicon can be contrasted with germanium which forms a stable solidmonosulfide.
