Sulfur mononitride is an inorganic compound with the formula SN. It is the sulfur analogue of the radical nitric oxide, NO. It can be produced through electrical discharges in mixtures of nitrogen and sulfur compounds, as well as the reaction of nitrogen with sulfur vapor.[1] In outer space, this compound was first detected in the giant molecular cloud Sgr B2. It was subsequently observed in cold dark clouds and in the comae of comets.[2]

Bonding

The valence electrons of this compound match those of nitric oxide. Unlike NO, NS reacts upon condensation to form polythiazyl or tetrasulfur tetranitride. Sulfur mononitride can be described as some average of a set of resonance structures, one of which has a bond order of one accompanied by charge separation.
