Two interlocking Au6 rings, whose individual metal atoms are linked through ethynyl ligands, are present in the title compound [{Au(C CtBu)}6]2. This novel homoleptic organometallic [2]catenane spontaneously self-assembles in the reaction of [Au(NH3)2]BF4 with tBuC CH. Weak AuAu interactions may contribute to the self-assembly of the structure. The bonding in one ring is shown schematically on the right.
