Abstract

Abstract The electrochemical reduction of the solvated cations M 2+ (M = Fe, Co, Ni) and of their cryptates (221, M) 2+ and (222,M) 2+ has been studied on a mercury electrode, in propylene carbonate, by normal and reverse pulse polarography, by cyclic voltammetry and by potentiostatic coulometry. The in situ complexation of the cations M 2+ by the macrobicyclic ligands (221) and (222) has been observed. An unusual polarographic behaviour is observed with the cryptate (221, Ni) 2+.
