Raman- and IB-spectra of four compounds of the general composition TlelsMt/» ( I4 ) [ *» : formal valence of the M-atom, M — Ag, Au, Pb and ( Bio.5Tl0.ft ) ] were investigated in order to identify the polyiodide species present. In accordance with structural results comparable amounts of I4 2- and l3-/I--groups were found for M = Ag, Pb and ( B10.0TI0.5)» while in TleleA^^ ) Ia~/I~groups predominate.
