The electrochemical oxidation of cadmium amalgam was studied in the nonaqueous solvents CH 2 Cl 2 , 1,2‐C 2 H 4 Cl 2 and propylene carbonate. Significant coordination effects were observed between the electrogenerated Cd(II) ions and 18‐membered macromonocyclic ligands, each containing six Lewis bases heteroatoms: 18‐O 6 , 18‐S 6 , 18‐N 2 O 4 , and 18‐N 6 . The stoichiometries and the stabilities of the resulting complexes were determined. These stabilities increase from 18‐O 6 or 18‐S 6 to 18‐N 6 .
