Mono- and diplatinum plumbylene complexes are prepared in which the bonding comprises synergic σ donation between the Pt and Pb atoms. The bonding distinguishes the complexes from both the classical Fischer carbene bonding model and M→Pb dative-only bonding. The Pt-Pb bond of the monoplatinum complex is stable, while the diplatinum complex reversibly loses one Pt fragment.
单核和双核铅基金属茂配合物的合成中,Pt 和 Pb 原子之间存在协同的 σ 给体作用。这种键合方式使配合物有别于经典的 Fischer 卡宾键合模型和 M→Pb 配位键合。单核铂配合物中的 Pt-Pb 键稳定,而双核配合物可可逆地失去一个 Pt 片段。
