An intensely and oxygen independent phosphorescent gold(I)-silver(I) complex: "trapping" an Au8Ag10 oligomer by two gold-alkynyl-diphosphine molecules.
The molecular heterometallic [{Au(8)Ag(10)(C(2)Ph)(16)}{(PhC(2)Au)(2)PPh(2)(C(6)H(4))(3)PPh(2)}(2)](2+) aggregate of unprecedented topology was obtained and structurally characterized; this compound demonstrates unusually effective phosphorescence, which displays negligible oxygen quenching due to shielding of emissive central cluster by the outer shell of the molecule.
