✦ Synopsis

Phosphorus is among the few elements that feature a large variety of allotropic modifications, polyanions, and clusters. [1, 2] The discovery of elemental phosphorus lies far in the past but scientists continue to make exciting new experimental findings, among which the recent discovery of fibrous phosphorus ought to be mentioned. [3] Extensive research is also devoted to theoretical calculations of seemingly limitless varieties of phosphorus clusters. [4] Among these clusters, however, highly charged clusters and polyanions are poorly studied because of their lower stability. As a rule, the bonding in phosphorus clusters and polyanions is of twocenter, two-electron type, and the formal oxidation states can be easily assigned to each phosphorus atom according to the number of homonuclear bonds it makes. [5] Typically, the clusters and polyanions are constructed by phosphorus atoms
