Triiodide
From Wikipedia, the free encyclopedia
Triiodide is an anion composed of three iodine atoms.
The following equilibrium :
I2 + I− → I3−
gives rise to the triiodide ion in solution. The Lewis base is the iodide ion and the Lewis acid is iodine. The reaction is endothermic. The central atom of I3− is sp3d hybridised, and the ion thus has linear shape according to VSEPR theory. Triiodide appears yellow in low concentration, and brown at higher concentration.
