Octahedral fac(S)-[Con(III)(aet)₃] molecules (aet = NH₂CH₂CH₂S^-) react with square-planar Pd(II) ions to form a sulfur-bridged Co₂/(III)Pd(II) trinuclear complex [Pd{Co(aet)₃}₂]²⁺, accompanied by the geometrical isomerization from fac(S) to met(S). This complex was found to act as a sulfur-donating trinuclear-metalloligand toward linear Au(I) and Ag(I) ions to afford Co₄/(III)Pd₂/(II)M₂/(I) metallacycles with 16 chiral centers, [M₂/(I){Pd(II)[Co(III)(aet)₃]₂}₂]⁶⁺ (M = Ag, Au (1)), which were successfully resolved into the (Δ)₄(R)₁₂ and (Λ)₄(S)₁₂ enantiomers.
