The reaction of [HgBr2{Co(aet)(2)(en)}](+) with [Ni{Co(aet)(2)(en)}(2)](4+) selectively gave the meso isomer of an S-bridged (CoHgCoIII)-Hg-III-Co-II trinuclear complex DeltaLambda-[Hs{Co(aet)(2)(en)}(2)](4+) (DeltaLambda-[1](4+)), while the optically active DeltaDelta isomer of [1](4+) was produced by the corresponding reaction with trans(N)-[Co(D-pen-N, O, S)(2)](-).
