Reaction of H 2 L ( 1 ) with potassium or strontium hydride, or lanthanum(III) chloride, followed by iron(III) chloride, yielded the {2}‐ironcryptates 2a – c . The mono‐, di‐, and trivalent guest cations are endohedrally encapsulated. In contrast, the dinuclear trispyridinium ironcryptand 2d was generated from the reaction of H 2 L ( 1 ) with only iron(III) chloride. The potassium metallacryptate 2a′ was formed from the triple‐helicate 2d by addition of potassium carbonate. The new compounds 2b , 2c , and 2d were unequivocally characterised by X‐ray diffraction analyses.
