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.
