'''Polythiazyl''' (or Polysulfur nitride), created in 1974, was the first conducting inorganic polymer. In addition to being an electrical [[Conductor (material)|conductor]], it was also found to be a [[superconductor]] at very low temperatures (0.2 K).
Polythiazyl is synthesized from [[tetrasulfur tetranitride]] (S<sub>4</sub>N<sub>4</sub>) in the following way:
:S<sub>4</sub>N<sub>4</sub> + 8Ag <nowiki>→</nowiki> Ag<sub>2</sub>S + 2N<sub>2</sub>
:S<sub>4</sub>N<sub>4</sub> (w/ Ag<sub>2</sub>S catalyst) <nowiki>→</nowiki> 2S<sub>2</sub>N<sub>2</sub> (w/ 77K cold finger) <nowiki>→</nowiki> S<sub>2</sub>N<sub>2</sub>
:S<sub>2</sub>N<sub>2</sub> (@ 0°C, sublimes to surface) <nowiki>→</nowiki> thermal polymerization <nowiki>→</nowiki> (SN)<sub>x</sub>
