The <SUP>129</SUP>I Mössbauer effect has been applied to investigate 2:3 molecular complexes of triphenylphosphine sulfide–iodine and acridine–iodine. The Mössbauer spectra indicate the presence of three unequivalent iodine sites (I<SUB>A</SUB>, I<SUB>B</SUB>, and I<SUB>C</SUB>), as expected from the crystallographic data of these complexes. The iodine atom (I<SUB>A</SUB>) coordinating to the sulfur or nitrogen atom of each donor molecule is more positively charged than that of the 1:1 molecular complex containing the same donor atom. This result can be interpreted in terms of the covalency of the S···I<SUB>A</SUB> or N···I<SUB>A</SUB> bond. The degrees of charge transfer in the 2:3 complexes are close to those in the 1:1 complexes, and the transferred charges are mainly localized on the terminal iodine atoms (I<SUB>B</SUB>). The iodine molecule (I<SUB>C</SUB>) cross-linked to two I<SUB>B</SUB> atoms has a slightly negative charge, consistent with the bond distance of the molecule. The iodine moieties of these complexes are very similar to the structure of I<SUB>8</SUB><SUP>2−</SUP> in Cs<SUB>2</SUB>I<SUB>8</SUB>.
