Abstract

A new Zintl cluster [Ge9PdPPh3]3− has been isolated as (2,2,2-crypt)K+ salt through the reaction of K4Ge9 and Pd[PPh3]4 in ethylenediamine solutions and characterized via single-crystal X-ray crystallography. The as-prepared bimetallic [Ge9PdPPh3]3− cluster could successfully trap a nickel atom to form a trimetallic cluster [Ni@(Ge9PdPPh3)]2−. The coordination of Ge94− by PdPPh3 induces a one-electron oxidation and encapsulation of the Ni atom into the Ge93− cage leads to a further one-electron oxidation and a geometry transformation from C4v (nido) to C3v (closo).
