Electron phonon coupling is the mechanism by which Cooper pairs are formed in conventional superconductors. Under this assumption, we can proceed to estimate a critical superconducting temperature, Tc of 0.5 K (see the methods section). This low temperature corresponds to an estimated superconducting gap of 0.03 meV, and a relatively low electron-phonon coupling constant λ of 0.3, which places this material in the weak coupling limit. We note several caveats associated with our specific Tc prediction. For one, the location of the Van Hove singularities responsible for the large DOS near the Fermi level are affected by the level of theory (Figure ). Partly for this reason, we have not investigated the effects of anharmonicity on Tc. Organic superconductors are furthermore not always of the conventional variety, and there are reasons to suspect that other coupling mechanism may be in play in a real material. Because rhodizonate anions can sustain multiple different charge states (Table ), Cooper pair formation in K3C6O6 and related materials might, for example, be driven by red-ox lattice instabilities. Other possibilities is electronic coupling via polaron and bipolaron and polarization waves arising in a localized core-electron framework. The latter models or mechanisms, which we are not able to evaluate computationally, imply an importance of polarizability. Large organic anions of high charge are amongst the most polarizable material constituents possible.
