It was the first conductive inorganic polymer discovered[1][2] and was also found to be a superconductor at very low temperatures (below 0.26 K).[3][4] It is a fibrous solid, described as "lustrous golden on the faces and dark blue-black", depending on the orientation of the sample. It is air stable and insoluble in all solvents.[5] It was first observed in 1910.[6] Structure and bondingThe material is a polymer. The S and N atoms on adjacent chains align.[2][7][8] Several resonance structures can be written.[9] SynthesisPolythiazyl is synthesized by the polymerization of the dimer disulfur dinitride (S2N2), which is in turn synthesized from the cyclic alternating tetramer tetrasulfur tetranitride (S4N4).[2] Conversion from cyclic tetramer to dimer is catalysed with hot silver wool.[2][1][15] S4N4 + 8 Ag → 4 Ag2S + 2 N2 S4N4 (w/ Ag2S catalyst) → 2 S2N2 (w/ 77K cold finger) → S2N2 S2N2 (@ 0°C, sublimes to surface) → thermal polymerization → (SN)x UsesDue to its electrical conductivity, polythiazyl is used in LEDs, transistors, battery cathodes, and solar cells.[10] References1. ^1 2 {{ Greenwood&Earnshaw | pages = 725–727 }} 2. ^1 2 3 {{Cite journal|last=Goehring|first=Margot|last2=Voigt|first2=Dietrich|date=1953|title=Über die Schwefelnitride (SN)2 und (SN)x|url=http://link.springer.com/10.1007/BF00628990|journal=Die Naturwissenschaften|language=de|volume=40|issue=18|pages=482–482|doi=10.1007/BF00628990|issn=0028-1042|via=}} 3. ^{{ cite journal | title = Polysulfur Nitride - a Metallic, Superconducting Polymer |author1=Labes, M.
