摘要
Abstract Carbones are divalent carbon(0) species that contain two lone pairs of electrons. Herein, we have prepared the first known stable and isolable free bis ‐(carbone) pincer framework with a well‐defined solid‐state structure. This bis ‐(carbone) ligand is an effective scaffold for forming monometallic (Ni and Pd) and trinuclear heterometallic complexes with Au−Pd−Au, Au−Ni−Au, and Cu−Ni−Cu configurations. Sophisticated quantum‐theoretical analyses found that the metal–metal interactions are too weak to play a significant role in upholding these multi‐metallic configurations; rather, the four lone pairs of electrons within the bis ‐(carbone) framework are the main contributors to the stability of the complexes.
