Carbon monosulfide is a chemical compound with the formula CS. This diatomic molecule is the sulfur analogue of carbon monoxide, and is unstable as a solid or a liquid, but it has been observed as a gas both in the laboratory and in the interstellar medium. [1] The molecule resembles carbon monoxide with a triple bond between carbon and sulfur. The molecule is not intrinsically unstable, but it tends to polymerize in sunlight to a brown mass, as first discovered in 1868 and 1872. [2] The polymer is quite stable, decomposing a little at 360 °C to carbon disulfide. This tendency towards polymerization reflects the greater stability of C–S single bonds.

Polymers with the formula (CS)n have been reported, [3] and the formal dimer is ethenedithione. Also, CS has been observed as a ligand in some transition metal thiocarbonyl complexes such as Fe(CO)4CS. [4]

The simplest carbon monosulfide synthesis decomposes carbon disulfide in a high-voltage AC arc. [5]
