How Encapsulated is a Sodide? Li+Na--EtNH2 vs Li+e--EtNH2

We have recently begun to look at how large, polarisable alkalides (group 1 metal anions) are solvated in solution. This proposal aims to determine how ethylamine is able to cosolvate a sodide in the presence of lithium, and determine whether there is a long-range liquid structure as found in the case of methylamine. We will directly compare this with the analogous solvated electron system, using a combination of neutron scattering, ab initio molecular dynamics and empirical potential structure refinement.
