报道了一种独特的金属在三角形钯夹心簇合物边缘的加成。虽然平行夹心配合物的边缘配位位点是狭窄的，因为两个空间位阻π-配体，缔合的额外的金属原子的金属片给出了更宽的配位位点。结果表明，在Pd-3片层夹心配合物中，附加金属原子对Pd-3的键合起着至关重要的作用。
A unique metal addition to the edge of a triangular palladium sandwich cluster is reported. While the edge coordination sites of a parallel sandwich complex are narrow because of two sterically encumbering pi-ligands, association of an additional metal atom to a metal sheet gives a wider coordination site. It was proved that the additional metal atom plays a crucial role in binding of cyclopentadienyl by a Pd-3 sheet sandwich complex.
