We think that K3C6O6 is important also because it can be thought of as a template for discovering (and engineering) a new family of one-dimensional π-based superconductors. πband superconductors are rare and great efforts have been dedicated to their study. Two-dimensional superconductors such as the experimentally known, LiC6, 88 and CaC6 89 or the theoretically predicted LiC12, 86 AlC8, and HPC3 have shown that intralayer π-systems can couple to in-plane vibrational phonon modes associated with covalent bonds, resulting in strong electron-phonon coupling and Tc values up to 30 K. K3C6O6 is different as superconductivity in it is predicted to be predominantly mediated through inter-, and not intra-, molecular π-interactions. We attribute the low Tc calculated for K3C6O6 to two main factors: A low electron phonon coupling strength λ, and a low average phonon frequency, 𝜔. The mathematical relationships that connect λ, 𝜔 and the number of states N near the Fermi level, to Tc are provided elsewhere. What is essential for our discussion is that these parameters can be rationally altered (we want them to increase) through chemical and physical manipulation of K3C6O6. We wish to open the door to such manipulation by sharing a collection of rationales. Superconductivity in K3C6O6 is intricately linked to a single pair of frontier π-bands. This simplicity, which results from the quasi-one-dimensional nature of the material, allows for relatively straightforward band engineering. The Fermi surface shown in Figure is the subset of the frontier π-bands that correspond to the highest occupied orbitals, resolved in reciprocal space. These levels are essential for superconductivity. The electron phonon coupling strength λ reflect the average movement of these levels (or levels near them) upon phonon perturbation. Doping is one direct way of changing the electron phonon coupling strength λ, and we can qualitatively predict how without calculations. If K3C6O6 were to be negatively doped, its Fermi level would move up. The effects of this are clear from our COHP bonding analysis (Figure ): with n-doping the orbitals near the Fermi level becomes less bonding. At half-filling, levels at the Fermi level would be effectively non-bonding, i.e., be equally bonding and anti-bonding. Such situations are characteristic of transition states, phase instability, and we would expect electron phonon coupling to increase. If n-doped K3C6O6 were to become unstable it is likely to undergo a Peierls distortion that dimerizes the rhodizonates. Such dimerization would split the two frontier π-bands into two sets, separated by a gap. The predicted P1 phase of K3.5C6O6 is one such example, in which the lowest pair of π-bands are filled by three quarters (2 electrons due to dimerization in K3C6O6, and 1 electron from the doping) instead of one quarter as in K3C6O6. With such band filling we expect the Fermi surface to be dominated by antibonding states (Figure and). Antibonding levels will naturally respond stronger than bonding levels to changing orbital overlap and should therefore be coupled stronger to low frequency phonon modes that compress and extend the rhodizonate stacks. Unfortunately, the ground state we predict for K3.5C6O6 is much too large, and of too low symmetry, to permit meaningful electron-phonon calculations that would test this hypothesis.
