Two types of intermetalloid cluster architectures are obtained from reactions of binary Zintl anions (Tt 2 Pn 2 ) 2− (Tt=Ge, Sn, Pb; Pn=As, Sb, Bi) with [(PPh 3 )AuMe], as described by S. Dehnen and co‐workers in their Research Article on page 16638. While combinations of heavier atoms lead to reconstruction of the binary precursor to form {[AuTt 5 Pn 3 ] 2 } 4− (take a left turn), the lightest homologue yields [Au 6 (Ge 3 As)(Ge 2 As 2 ) 3 ] 3− with a new supertetrahedral Zintl cluster architecture (take a right turn) upon an atom exchange reaction that was rationalized by DFT calculations.
