Therefore, Manjón and coworkers suggest that the term hypervalent is unnecessary and it should be replaced by the word "hypercoordinated" in ERMBs and EDMBs The reason is that for defenders of the hypervalent model, the kind of bonding is not given by the number of electrons shared between two atoms (around one in PCMs) but by the electron configuration of the involved atoms. This idea is not shared by us nor by Wade (see last chapter in Ref. an additional example here on we illustrate how electron-rich elements, such as iodine, can form linear electron-rich bonds in three-center molecules (I3 -) and linear electrondeficient bonds when these bonds extend beyond three centers, as it is the case of infinite linear iodine chains. We hope this will help the supporters of the hypervalent bonding model to consider their position regarding the electron-deficient character of bonding in PCMs.
