Abstract

A new dinuclear gold(I) complex, possessing a bridging diphosphine ligand (1,2-bis(diphenylphosphino)ethane) and two terminal thiol ligands (1-thioglycerol), was synthesized and fully characterized by IR, 1H and 31P NMR, fluorescence, ESI-mass, and diffuse reflection spectroscopy, together with X-ray diffraction and elemental analyses. The compound formed a 1D chain supramolecular structure through intermolecular aurophilic interactions in the crystal structure, leading to photoluminescence in the solid state.
