利用含双硫族碳(0)(BChC)的亚氨基硫烷配体成功地合成和分离了单核、双核和四核银配合物1-3。在这些配合物中,BChCs以κ2C,N和κ3C,C′,N配位。[Ag 4(BChCs)2](TfO)4(3)的分子结构揭示了BChC的特殊电子结构,即中心碳原子上有两个孤对电子。此外,3的结构提供了第一个实验证明,碳可以作为多齿配体在多阳离子簇。
Mono-, di-, and tetranuclear silver complexes 1–3 were successfully synthesized and isolated using a bis(chalcogenane)carbon(0) (BChC)-bearing iminosulfane ligand. In these complexes, BChCs exhibit κ2C,N and κ3C,C′,N coordination modes. The molecular structure of [Ag4(BChCs)2](TfO)4 (3) reveals the peculiar electronic structure of BChC, which features two electron lone pairs on the central carbon atom. Furthermore, the structure of 3 provides the first experimental proof that carbones can act as multidentate ligands in multication clusters.
