In the infinite linear chain, each iodine atom has 6 electrons forming three pairs of nonbonding LEPs, as previously commented, that are perpendicular to the linear chain and show a sp 2 geometrical configuration that minimizes the electronic repulsion between In the infinite zigzag chain I∞(1 � ), each I atom has four electrons distributed in two LEPs and the three remaining electrons should be shared between the two next-neighbor iodine atoms. In this chain, all I atoms show a sp 3 configuration to minimize the electronic of compounds featuring ERMBs and EDMBs allows us to prompt the supporters of the hypervalent bonding model in PCMs to reconsider their positions in relation to the type of bonding present not only in PCMs, such as rocksalt GeTe, but also in all other electronrich molecules and solids as it is here the case of the infinite linear iodine chain.
