Triiodide ion, organic iodine complex, phenazine
A structural study of the polyiodide containing species C12H9N2+ I3- C12H8N2 · 1/6I2 was carried out by single crystal X-ray diffraction techniques. The material crystallizes in the monoclinic space group C2/m with a= 16.561(5), b = 8.372(2), c = 9.908(5) A and β = 111.24°. There are two molecules per cell. Dara were collected using Mo Kἀ radiation and refinement converged to R = 0.027 based on the 1996 unique reflections with |Fo|≥3δ(Fo). The iodine atoms were found coexist in two distinct moieties, an I2 and an I3 - (symmetric and linear). The iodine-iodine distance are 2.64(1) and 2.917 (1) A, respectively. The I2 site is only 1/6 occupied.
