title: Proton-controlled formation and interconversion of Au(I)2Ni(II) trinuclear and Au(I)4Ni(II)3 heptanuclear complexes with mixed thiomalate and bis(diphenylphosphino)ethane.
abstract: Treatment of a newly prepared digold(i) complex, [Au2(dppe)(H2msa)2] ([H41]; dppe = 1,2-bis(diphenylphosphino)ethane, msa = thiomalate), with Ni(2+) 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.
