In the last few years, a controversy has been raised regarding the nature of the chemical bonding present in phase change materials (PCMs), many of which are minerals such as galena (PbS), clausthalite (PbSe), and altaite (PbTe). Two opposite bonding

An unconventional bond has been recently proposed to be present in the crystalline phases of phase change materials (PCMs), that has been quoted as electron-rich multicenter (ERM), hypervalent, 3 center-4 electron, resonant, or metavalent bond. It ha
