A series of luminescent dinuclear gold(I) thiolates, [Au2Ph2PN(R)PPh2}(SR′)2](R = C6H11, R′= C6H4F-p, C6H4Cl-p, C6H4Me-p; R = Ph, R′= C6H4Me-p; R = Prn, R′= C6H4Me-p; R = Pri, R′= C6H4Me-p) have been synthesized and their photophysical properties studied. The crystal structure of [Au2Ph2PN(C6H11)PPh2}(SC6H4F-p)2] has been determined. These complexes have been shown to exhibit low-energy emission at ca. 600 nm, attributed to a ligand-to-metal charge transfer (thiolate to AuI) origin.
