Complete control : Versatile self‐assembly of the L ‐cysteinato Co III Hg II Co III trinuclear complex into dimeric, metallohelix, and metallocage structures, which is induced by deprotonation of L ‐cysteine carboxyl groups, is reported. Remarkably, the homochiral (Λ L Λ L ‐Co III Hg II Co III ) 6 metallocage, which encapsulates an aqua metal ion, was formed from the meso ‐like Δ L Λ L isomer of this trinuclear complex, as well as from its Λ L Λ L isomer (see scheme).
