Luminescence studies of dinuclear gold(I) phosphor-1,1-dithiolate complexes

Abstract Luminescence properties of several structurally characterized dinuclear gold(I) complexes with phosphor-1,1-dithiolato type ligands were investigated. Among these complexes, single crystal X-ray analyses revealed structural types, where weak intermolecular Au⋯Au interactions (∼2.90–3.20 A) were present in some cases and absent in others. This interaction showed a profound influence on the observed emission spectra for the title complexes. A clear correlation between the emission profiles of these gold–sulfur complexes and the presence of intermolecular Au⋯Au interactions in the solid state has been established.
