title: Unusual 14-electron fragments [Pd(η(3) -Bi3-x Pbx )]((x+1)-) as pseudo lead atoms in closo-[Pd@Pd2 Pb10 Bi6 ](4-).
abstract: How to simplify a complex thing: A salt of the heaviest intermetalloid cluster known to date, [K([2.2.2]crypt)]4 [Pd@Pd2 Pb10 Bi6 ]⋅2 en, resulted from a reaction of [Pd(PPh3 )4 ] with [K([2.2.2]crypt)]2 (Pb2 Bi2 )⋅2 en in ethane-1,2-diamine (en). The electron number of the ternary intermetalloid anion accords with Wade-Mingos rules, as the [Pd(η(3) -Bi3-x Pbx )]((x+1)-) (x=0, 1) 14-electron fragments formed in situ are isolobal with Pb atoms.
