Note:

a: The logarithms of the equilibrium constants and chemical shifts of the complexes were calculated based on experimental values of chemical shifts data under conditions of rapid exchange.

b: Calculated from NMR signal width.

c: An experimental value of the width of the NMR²³NaNCS signal in the absence of ligand

d: Calculated signal width of the NMR²³NaL⁺
