“…48 Information on the silver-carbon bond distance suggests a value of 2.06 Å be used. 49,50 The value of the carbon-nitrogen bond distance in these works, however, is unusually low, so the value of 1.17 Å assigned in the NaCN and KCN studies, which closely matches our quantum simulation results for the embedded monomer, was assigned.…”

“…In the sodium chloride host, ground state AgC distances are generally in the 2.11−2.13 Å range and the CN distance is consistently around 1.19 Å. These values are slightly longer than what is observed in crystallographic studies of the pure potassium silver dicyanide compounds [AgC = 2.12(14) Å; CN = 1.17(20) Å] and other simple silver dicyanide salts [AgC = 2.05−2.07 Å; CN = 1.13−1.14 Å] . We suspect that by altering the metal center orbital, equatorial halide ligands are responsible for this small elongation.…”

Calculated silver chloride distances (2.92-3.05 Å) are highly variable depending on the dimer configuration.…”
