dc.description.abstractReaction of the yellow-green emitters [Au{(PPh2) 2C2B9H10}(PR3)] with [Au(C6F5)(tht)] affords orange-red emissive gold complexes [Au2{ο-(PPh2)2C2B 9H10}(C6F5)(PR3)] which contain different neutral (PR3) and anionic (C6F 5) auxiliary ligands and an anionic diphosphine. The resulting complexes are among the few reported in which an ortho-carborane diphosphine acts in a bridging mode, and are unique in containing not a closo- (neutral), but a nido-carborane (anionic) cluster. DFT and TDDFT calculations led to the prediction of the origin of the two first singlet-triplet transitions, which is consistent with the experimental results. Although the blue emissive nido-diphosphine plays a key role in the transitions of the three-coordinate precursors and the final dinuclear complexes, it is the environment around the gold centre that controls the emission energy. © The Royal Society of Chemistry 2011.-
