A Molecular Description of Superconductivity of Sulfur Hydride and Related Systems under High-Pressure Conditions

“…With the demonstrated coherence for the off-centering of the proton resulting in a ratio between the long and short SH bonds of a factor 1.667, it will be clear that the compactness of the structure as suggested will be strongly reduced in the R3m phase compared with the optimal symmetrization in the ideal cubic structure (this factor decreases in the order of 1.667, 1.500 to 1.334 for proton-, hydrogen atom-to hydride-like, respectively, demonstrating a regular decrease) [11] [12] [13]. We presume that for interrelated models under pressure there is a slightly distorted symmetry in order to accommodate the hydrogen network resulting in a decrease of bond distances.…”

“…Symmetry changes under high-pressure conditions were among others noticed by Edwards 3 X by substitution of X with nucleophiles via a trigonal bipyramidal state, in which the transferred carbon may be described as a methyl planar triangle cation [11]. Ab initio calculations based on a linear threecenter two-, three-and four-electron type of bonding clearly portrayed in combination with the dynamics of the Van't Hoff concept, as described by us in various papers, give a good description of the exclusivity of the network in its role as superconducting system.…”

“… the bond distance of C-X in the pentavalent state, and the tetrahedral angle θ, the following characteristics can be given [11] [12]: In all these cases for proton dynamics we are dealing with hydrogen-bond symmetrization in their transition intermediates. Energy minima has been calculated based on cage compounds with geometrical variation.…”
