TABLE 1.

Average number (and standard deviation) of contacts between water, oxygens from CO, and Cl⁻ anions participating in the first coordination sphere of each cation. The radius of the first coordination sphere was taken from the RDF calculations. Just the last 180 ns were considered for the analysis.
