Abstract

Treatment of a newly prepared digold(I) complex, [Au2(dppe)(H2msa)2] ([H41]; dppe = 1,2-bis(diphenylphosphino)ethane, msa = thiomalate), with Ni2+ gave two interconvertible multinuclear complexes, [Ni{Au2(dppe)(msa)2}]2− ([2]2−) and [Ni3{Au2(dppe)(Hmsa)2}{Au2(dppe)(msa)2}(MeOH)3] ([3]), dependent on solution acidities.
