This new parameter, the cation ratio of structural stability (CROSS), incorporates the inverse of the critical flocculation (or coagulation) concentration (Rengasamy and Sumner 1998; Sposito 2008) for a cation as a measure of its 'relative flocculating power,' which is taken as a chemical basis for distinguishing cations that promote soil particle aggregation from those that promote soil particle dispersion.
We can easily deduce that when the diameter of the alkaline cation match well with the cavity size of the crown ether of CoL, could the stable alkaline cation complex formed, the complexation would more effectively favor it to approach and control the microenviroment around the coordinated cobalt ion, and favor the formation and stabilization of Co(II)-O2 bond.
