La cage aux folles: The [Eu@Sn6Bi8]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 EuII ion with the main-group-metal cage. ESI mass spectrometry suggest that the cage forms from two seven-atom hemispheres.
