In light of the above arguments, we would also like to suggest a revision of commonly accepted formal building blocks for polyiodides, traditionally I2, I3 -and I -fragments. In a sense, the inclusion of I -has always been somewhat problematic. I -is a fragment which, if strongly representative, would imply that the In x-chain, i.e. the molecule/anion, is broken somewhere or almost so, i.e. it would not be a molecule. We advocate here for the following alternative: polyiodides are made of I2, I3 -and I•I fragments, as above discussed, i.e. they are made of covalent-(2c-2e), electron-rich multicenter-(3c-4e), and electron-deficient multicenter-like bonds (2c-1e). This very simple view suggests the inclusion of long I•I EDMBs within a picture of normality for these systems and provides a theoretical framework (easily accessible via penand-paper means) to rationalize them. This is important as it reduces the sense that polyiodides are formed by simple building blocks "glued" together by mysterious forces, and rather passes the idea that we have a good general model for them. Bond length variability seems to mostly arise from the compromise that needs to be made in maintaining a formal count of 2n electrons for n bonds, like in any typically covalent setting, without exceeding the octet rule significantly for any atom. The impossibility of extending 3c-4e ERMBs over more than 3 centers creates, under a valence bond (VB) setting, preferred resonant formulas, also contributing to bond length alternation. The view of chains of covalent bonds, ERMBs, and EDMBs also resolves some issues connected with the interpretation of the Raman spectra of polyiodides, which were reduced to I2 and I3 -fragments eventually perturbed. The nature of the invoked perturbation appears now much clearer and changes in bond force constants for the three possible bond types are both expected and rationalized.
