A series of polynuclear gold(I) sulfido
complexes of bis(diphenylphosphino)amine
ligands has been synthesized and characterized. A rather small variation
in the conformation of the bis(diphenylphosphino)amine ligands has
led to distinct differences in the identity of the polynuclear gold(I)
sulfido complexes formed. Unprecedented concentration-dependent and
solvation-dependent reversible cluster-to-cluster transformation between
a dodecanuclear gold(I) sulfido complex (LMe-Au12) and a
hexanuclear gold(I) sulfido complex (LMe-Au6) has been observed.
The transformation process has been monitored not only by 1H and 31P{1H} NMR spectroscopy but also by
UV–vis absorption spectroscopy and high-resolution electrospray
ionization mass spectrometry (HR-ESI-MS) in the solution state. This
work has provided a simple approach to achieve structure modulation
of gold(I) sulfido complexes and an understanding of supramolecular
transformations via external stimuli.
