Isostructural Coordination Capsules for a Series of 10 Different d5–d10 Transition‐Metal Ions

Ten of a kind: A series of {M6L8} octahedral metallocapsules that are structurally identical except for the metal at the apexes was quantitatively prepared from tris-monodentate ligands L and ten divalent d5–d10 transition-metal ions (see picture). Six CF3SO3− anions coordinated inside the capsules can be site-selectively replaced with other anionic ligands to functionalize the cavity.
