Syntheses, properties and structures of nanosized palladium CO/PR(3)-ligated homo- and heterometallic clusters containing up to 165 metal atoms are the focus of this review. The work discussed is primarily that of the authors and their coworkers. We propose that the unparalleled variety of structural types and the distinctive reactivities of neutral Pd(n)(CO)(x)(PR(3))(y) clusters composed of zerovalent Pd atoms are a consequence of relatively weak Pd-L(ligand) and Pd(0)-Pd(0) interactions that result from the stable 5s(0)4d(10) closed-shell electron configuration of atomic Pd in its ground state.
本文综述了纳米钯 CO/PR(3)-键合同核和异核金属簇合物的合成、性质和结构，这些簇合物中金属原子的数量多达 165 个。本文讨论的工作主要是作者及其同事的工作。我们提出，由零价钯原子组成的中性 Pd(n)(CO)(x)(PR(3))(y) 簇具有无与伦比的结构类型多样性和独特的反应性，这是由于原子钯基态下稳定的 5s(0)4d(10) 满壳层电子构型导致的 Pd-L(配体)和 Pd(0)-Pd(0)相互作用相对较弱所致。
