La cage aux folles : The [Eu@Sn 6 Bi 8 ] 4− anion (see picture: Sn/Bi blue/orange, Eu black) is the first example of an intermetalloid cluster anion that embeds a lanthanide ion in the solid state. Magnetic measurements and calculations both point to an S =7/2 ground state and indicate ionic interactions of the Eu II ion with the main‐group‐metal cage. ESI mass spectrometry suggest that the cage forms from two seven‐atom hemispheres.
