Polythiazyl

Polythiazyl (polymeric sulfur nitride), (SN)_x, is an electrically conductive, gold- or bronze-colored polymer with metallic luster. It was the first conductive inorganic polymer discovered, and was also found to be a superconductor at very low temperatures (below 0.26 K).

Structure and bonding

Several resonance structures can be written:

Synthesis

Polythiazyl is synthesized by the polymerization of the dimer disulfur dinitride (S₂N₂), which is in turn synthesized from the cyclic alternating tetramer tetrasulfur tetranitride (S₄N₄). Conversion from cyclic tetramer to dimer is catalized with hot silver wool.

Uses

Due to its electrical conductivity, polythiazyl is used in LEDs, transistors, battery cathodes, and solar cells.
