The birdcage : The title anion, which contains two endohedral d 10 metal atoms, is the second known ternary cluster anion comprising only metal atoms (see picture: Sn orange, Sn/Bi blue, Ni black). The K([2.2.2]crypt) salt was obtained upon reaction of the binary precursor [Sn 2 Bi 2 ] 2− with [Ni(cod) 2 ] in ethylenediamine / toluene by a complicated fragmentation/re‐arrangement process. X‐ray diffraction and DFT calculations confirm the composition of the anion.
