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 Ge-9(4-) by PdPPh3 induces a one-electron oxidation and encapsulation of the Ni atom into the Ge-9(3-) cage leads to a further one-electron oxidation and a geometry transformation from C-4v (nido) to C-3v (closo).
