L6–L8, or glycylglycylglycine, L11. The advantages of the planarligand field and the small cavity size are reflected in the ready attainment of a d8 Cu3+ complex as demonstrated by the extremely low electrode potential EΘ measured using cyclic voltammetry. In contrast, Ni2+ with a smaller cation size seems to fit more easily in the 12-membered cavity. The KNiH–2L value is comparable to that for L11
