Monosulfur dinitride is an inorganic chemical compound of sulfur from the group of covalent nitrides . In addition to disulfur dinitride , tetrasulfur dinitride , pentasulfur hexanitride , tetrasulfur tetranitride , monosulfur mononitride , oligosulfur dinitrides and polymeric polythiazyl (SN) _x, the compound belongs to the group of sulfur-nitrogen compounds or sulfur nitrides . The connection is isovalentelectronic with the nitrous oxide .

It is formed as a short-lived intermediate stage in the decomposition of phenylthiatriazole.

Monosulfur dinitride quickly breaks down into nitrogen and sulfur.
