The first homoleptic trinuclear arylgold(i) complex, [Au3(L')2](NO3) (3), based on an ortho-phenyl metallated aryl-diphosphine ligand (L' = o-C6H4PPh(C15H10O)PPh2), has been obtained through a new thermolytic reaction of the corresponding diauracycle, [Au2(L)2](NO3)2 (L = xantphos). The formation of 3 involves activation of the ortho-phenyl C-H bond of the xantphos ligands. The presence of Au-C bonds in this new gold-diphosphine cluster is not its only remarkable feature, since it also displays two 12-membered rings fused together and a linear (Au3) chain with aurophilic interactions. Complex 3 exhibits strong sky-blue luminescence that can be assigned to a triplet metal-metal (3MM) transition partially mixed with a ligand-to-metal-metal charge transfer (3LMMCT) transition related to the aurophilic bonding. This [Au3(L')2]+ triauracycle also shows AIEE-activity, and is a selective luminescent chemosensor for metal ions.
