Thermodynamic analysis reveals that ScNreA complexation with native nitrate and nitrite or non-native iodide is an exothermic process. Further deconvolution of the association and dissociation kinetics for each anion reveals that the release event can be limiting, in turn, giving rise to the observed selectivity: nitrate > iodide > nitrite.
