WebThe polymorphism is essentially due to a different arrangement in the polyiodide network of the [I5] and [I3] components. The FT-Raman spectrum of 1-triclinic shows the characteristic bands in the range 200–50 cm 1 which are in good agreement with the structural features of the polyiodide network.
