Reactions of [{Ir(ppy or ppy-CF₃)₂} ₂(μ-Cl)₂] {Hppy = 2-phenylpyridine, Hppy-CF₃ = 2-[3,5-bis(trifluoromethyl)phenyl]-pyridine} with d-penicillamine (D-H ₂pen) afforded emissive IrIII mononuclear complexes [Ir(ppy or ppy-CF₃)₂(D-Hpen-N,S)] as a 1:1 mixture of the Δ_D/Δ_D isomers. These complexes were converted into Ir^IIIAg^IIr^III trinuclear structures in [Ag{Ir(D-pen-N,S)(ppy or ppy-CF₃)₂}{Ir(D-Hpen-N,S)(ppy or ppy-CF₃)₂}] by treatment with AgNO₃, which led to a drastic blueshift of the emission bands. Whereas the (ppy)Ir ^IIIAg^IIr^III complex produced the heterochiral Δ_DΔ_D isomer, the ppy-CF3 complex gave the homochiral Δ_DΔ_D and Δ_DΔ _D isomers that could completely be separated by crystallization. It was found that the quantum efficiency of the emission band for the Δ_DΔ_D isomer is much lower than that for the Δ_DΔ_D isomer.
