The evolving field of quantum materials would benefit from tunable fault-tolerance in the spin propagation within quantum spin liquids (QSL). α-RuCl3 is one candidate material to exhibit QSL properties and it has been hypothesized that ionic liquids (ILs) could be made to coat the crystal and gate the transfer of spin states increasing the reliability and reproducibility of signals permutated through the QSL. Herein we investigate a large set of candidate ILs for the interactions with α-RuCl3 and resulting geometric deviations in the α-RuCl3 structure. Trends with the ionic liquid structure and resulting changes to the α-RuCl3 lattice will be presented. Periodic DFT will be performed and analysis of the spin and electronic structure properties will be discussed.
