Unusual AuI−AgI heterometallic complexes [Au5Ag8(μ-dppm)4{1,2,3-C6(C6H4R-4)3}(C⋮CC6H4R-4)7]3+ (R = H 1, CH3 2, But 3) were isolated by reactions of polymeric silver arylacetylides (AgC⋮CC6H4R-4)n with binuclear gold component [Au2(μ-dppm)2(MeCN)2]2+ (dppm = bis(diphenylphosphino)methane), in which cyclotrimerization of arylacetylide −C⋮CC6H4R-4 affords trianion {1,2,3-C6(C6H4R-4)3}3- with an unprecedented μ5-bonding mode. Compounds 1(SbF6)3−3(SbF6)3 exhibit intense photoluminescence derived from an MLCT (Au5Ag8 → C⋮CC6H4R-4) transition, mixed with a metal cluster-centered excited states.
