Octahedral fac ( S )‐[Co III (aet) 3 ] molecules (aet=NH 2 CH 2 CH 2 S − ) react with square‐planar Pd II ions to form a sulfur‐bridged Co III 2 Pd II trinuclear complex [Pd{Co(aet) 3 } 2 ] 2+ , accompanied by the geometrical isomerization from fac ( S ) to mer ( S ). This complex was found to act as a sulfur‐donating trinuclear‐metalloligand toward linear Au I and Ag I ions to afford Co III 4 Pd II 2 M I 2metallacycles with 16 chiral centers, [M I 2 {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.
