(where D is a molecule containing the thione or selone groups as donors), all characterized
by x-ray diffraction, are reported. For the adducts with the thione compounds, which can be
considered weak or medium-weak complexes, an empirical linear correlation between the
frequency of the v (II) stretching vibrations and the d (II) bond distances has been found.

FT-Raman spectra of some polyiodides and of a series of D·I_2 chargetransfer complexes (where D is a molecule containing the thione or selone groups as donors), all characterized by x-ray diffraction, are reported. For the adducts with the thione compounds, which can be considered weak or medium-weak complexes, an empirical linear correlation between the frequency of the v(I-I) stretching vibrations and the d(I-I) bond distances has been found. Some polyiodides show FT-Raman spectra that are indistinguishable with respect to those displayed by the neutral complexes of weak or medium-weak strength; in such cases, the polyiodide can be regarded as a diiodine molecule, perturbed by an I_n^- (n = 1, 3, ...) donor. Polyiodides of this type show Raman absorptions falling in the linear correlation.
