Evidence suggests that NS can react with itself to reach NS, NS, and polymers of the form (NS). (NS) forms from polymerization of cyclo-NS.
Trans-NSSN results from direct dimerization of NS.
NS has been observed through photoelectron spectroscopy of vapors of the (SN), polymer, but has not yet been characterized further. Attempts to produce NS by oxidation of [PPN] [SN] were unsuccessful. Its theorized that rapid dimerization to (NS) will disproportionate irreversibly to NS and NS.
