Abstract/OtherAbstract:
A wide decomposition pressure range of 132 GPa is predicted for PbH_{4} above which it emerges in very different forms compared with its group-14 congeners. This triply Born-Oppenheimer system is a nonmolecular, three-dimensional, metallic alloy, despite a prominent layered structure. A significant number of enthalpically near-degenerate structures, with exceedingly small energy barriers for distortions, and characteristic instabilities in the phonon spectra suggest that even at very high pressures PbH_{4} may exhibit both metallic and liquidlike properties and sublattice or even full melting.
