The first mixed In/Sb Zintl anion, a cluster that effectively appears as [Sb@In 8 Sb 12 ] 4− , but actually is a 1:1 mixture of [Sb@In 8 Sb 12 ] 3− and [Sb@In 8 Sb 12 ] 5− , has been synthesized and structurally characterized, as shown by Z. M. Sun et al. in their Communication on page 8367 ff. The tri‐anion features perfect T h symmetry and contains eight equivalent In 3+ centers in a cube, while in the penta‐anion, the presence of two additional electrons induces a symmetry breaking, which substantially distorts the structure away from the T h symmetry.
