Tetrabutylammonium triiodide explained

Tetra-n-butylammonium triiodide (TBAI₃) is a quaternary ammonium salt with a triiodide counterion. It is a common carrier of the triiodide used in chemical synthesis of photovoltaic materials,^[1] organic conductors and superconductors.^[2] In crystals, the triiodide moieties are linear and shows high crystallinity.^{[3] [4]} The crystals have a black appearance with a needle or plate-like habit.
