合成了一个以Pd 4Ge 3为核的平面六方配合物[Pd{Pd（dmpe）}3（μ3-GePh 2）3]，并用X射线衍射、核磁共振和密度泛函理论对其结构进行了表征. 4-叔丁基苯乙醚将Pd 4转化为六钯配合物[{Pd 3（μ-GePh 2）2（μ-H）（μ3-GePh 2（SC 6 H4 tBu-4））}2（μ-dmpe）]，由两个Pd 3Ge 3单元通过dmpe配体桥接而成。CuI或AgI与Pd_4Ge_3形成[Pd（μ-MI）{Pd（dmpe）}_3（μ_3-GePh_2）_3]（M = Cu，Ag），其中Cu或Ag桥接了Pd_4Ge_3核的Pd-Pd键。溶液中的CuI加合物在NMR时间尺度上经历CuI在Pd 4Ge 3平面表面上的枢转运动。
A complex with a planar hexagonal Pd4Ge3core, [Pd{Pd(dmpe)}3(μ3-GePh2)3], was synthesized and characterized by X-ray and NMR measurements as well as by DFT calculations. 4-tert-Butylbenzenethiol converted the Pd4complex into a hexapalladium complex, [{Pd3(μ-GePh2)2(μ-H)(μ3-GePh2(SC6H4tBu-4))}2(μ-dmpe)], composed of two Pd3Ge3units bridged by a dmpe ligand. The addition of CuI or AgI to the Pd4complex yielded [Pd(μ-MI){Pd(dmpe)}3(μ3-GePh2)3] (M = Cu, Ag), in which Cu or Ag bridges a Pd–Pd bond of the Pd4Ge3core. The CuI adducts in solution undergo a pivot motion of the CuI on the surface of the Pd4Ge3plane on the NMR time scale.
