Abstract

Treatment of the racemic (Δ) ₂/(Λ) ₂ isomer of the tricationic complex, [Co ₃(aet) ₆] ³⁺ ([1] ³⁺), with the optically active (Λ _LLL) ₂ isomer of the trianionic complex, [Co ₃(L-cys-N,S) ₆] ^3- ([2] ^3-), afforded only the (Δ) ₂(Λ _LLL) ₂ isomer of the complex salt, [Co ₃(aet) ₆][Co ₃(L-cys-N,S) ₆] (3), the structure of which was determined by X-ray crystallography. The selective formation of this isomer was also observed when the racemic isomer of [1] ³⁺ was treated with a 1:1 mixture of the (Δ _LLL) ₂ and (Λ _LLL) ₂ isomers of [2] ^3-.
