五、Chemical significance
Our prediction that MAr42+(Sb2F11−1)2(M=Au,Ag,Cu) salt compounds can be stabilized simultaneously addresses the two fascinating challenges posed at the beginning of this article. Indeed, both a bulk salt compound containing a noble gas lighter than krypton and the congeners of AuXe42+(Sb2F11−1)2containing noble gases other than Xe can be synthesized. The near-zero estimate of the enthalpy change −0.666 kcal/mol of the also suggests that, in principle, synthesizing the bulk salt compound (where M is a suitable coordinating metal ion with a higher binding energy for Ne than Cu has for the noble gas but a smaller radius than the Cu ion), which is a light congener of AuXe42+(Sb2F11−1)2, is possible. Our results present new perspectives for future experimentation on these compounds.
