A Möbius arrangement of the bonds directly attached to a metallamacrocycle was observed for the Au I complex [Au 3 (CNC)(μ‐Ph 2 PCH 2 PPh 2 ) 2 ] + , which was self‐assembled by treating the lithium salt of pyridyl‐2,6‐diphenyl 2− (CNC) with [Au 2 Cl 2 (μ‐Ph 2 PCH 2 PPh 2 )]. The trinuclear Au I complex has intramolecular Au⋅⋅⋅Au and CH⋅⋅⋅π interactions, exhibits a remarkable stability in solution, and is cytotoxic toward cancer cell lines.
