Abstract
A Möbius arrangement of the bonds directly attached to a metallamacrocycle was observed for the AuI complex [Au3(CNC)(μ-Ph2PCH2PPh2)2]+, which was self-assembled by treating the lithium salt of pyridyl-2,6-diphenyl2− (CNC) with [Au2Cl2(μ-Ph2PCH2PPh2)]. The trinuclear AuI complex has intramolecular Au⋅⋅⋅Au and CH⋅⋅⋅π interactions, exhibits a remarkable stability in solution, and is cytotoxic toward cancer cell lines.
