Increasing the average phonon frequency 𝜔 by chemical substitution is a third approach for engineering a higher Tc in K3C6O6-derived materials. One way to effect such change is to select cations that contain strong covalent bonds to light elements, preferably hydrogen. Hydrogen bonding between such cations and the rhodizonate anions they bridge could couple high frequency R-H stretching modes to the metallic states of the rhodizonates. Our suggestions for modulating conductivity and enhancing πbased superconductivity are challenging to verify computationally. While we plan to theoretically explore the effects of some chemical modifications in future work, we encourage experimental pursuit and characterization of these systems.
