Finally, it must be stressed that the results of this work have very far-reaching consequences for the broad scientific community, especially for condensed matter scientists: i) they provide a comprehensive framework to understand how the 3c-2e bonds and in general EDMBs are formed in solid elemental and complex materials from primary ionocovalent ppσ-bonds plus secondary bonds involving LEPs and even in atomic/polymeric nitrogen and hydrogen (the last one with no p electrons), thus providing a new paradigm for describing many structures; ii) they show several descriptors that can be used to identify EDMBs at RP and HP in a wide variety of materials from simple elements to complex materials, such as PCMs, highly efficient thermoelectrics, and topological insulators, superconductors, and highly efficient photovoltaic materials; and iii) they open the door for a better understanding of the chemical bonding mechanisms in the above commented advanced materials for improving their performance . Additionally, we hope that this work will promote: i) further work to understanding EDMBs in solids and their associated exceptional property portfolio; and ii) a revision that helps to unify the notation, among the condensed matter physicists, chemists, and materials scientists of this well-known unconventional bond in molecules, but rather poorly known in solids.
