Abstract

The birdcage: The title anion, which contains two endohedral d10 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 [Sn2Bi2]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.
