A novel Au(I) Co(III) coordination system that is derived from the newly prepared [Co(D-nmp)2 ](-) (1(-) ; D-nmp=N-methyl-D-penicillaminate) and a gold(I) precursor Au(I) is reported. Complex 1(-) acts as a sulfur-donating metallaligand and reacts with the gold(I) precursor to give [Au2 Co2 (D-nmp)4 ] (2), which has an eight-membered Au(I) 2 Co(III) 2 metallaring. Treatment of 2 with [Au2 (dppe)2 ](2+) (dppe=1,2-bis(diphenylphosphino)ethane) leads to the formation of [Au4 Co2 (dppe)2 (D-nmp)4 ](2+) (3(2+) ), which consists of an 18-membered Au(I) 4 Co(III) 2 metallaring that accommodates a tetrahedral anion (BF4 (-) , ClO4 (-) , ReO4 (-) ). In solution, the metallaring structure of 3(2+) is readily interconvertible with the nine-membered Au(I) 2 Co(III) metallaring structure of [Au2 Co(dppe)(D-nmp)2 ](+) (4(+) ); this process depends on external factors, such as solvent, concentration, and nature of the counteranion. These results reveal the lability of the AuS and AuP bonds, which is essential for metallaring expansion and contraction.
