Abstract
Two types of intermetalloid cluster architectures are obtained from reactions of binary Zintl anions (Tt2Pn2)2− (Tt=Ge, Sn, Pb; Pn=As, Sb, Bi) with [(PPh3)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 {[AuTt5Pn3]2}4− (take a left turn), the lightest homologue yields [Au6(Ge3As)(Ge2As2)3]3− with a new supertetrahedral Zintl cluster architecture (take a right turn) upon an atom exchange reaction that was rationalized by DFT calculations.
