X-Ray crystal analysis of the latter showed a weak metal–metal interaction in the solid state with the shortest Au ⋯ Au separation being 3.153(2)Å. The gold(I)–acetylide complexes have long-lived and emissive 3(π,π*) excited states in solutions at room temperature. The photoreaction of [Au(PPh3)(CCPh)] with methyl viologen has been investigated by Stern–Volmer quenching and flash-photolysis experiments.journal article10.1039/DT99300029292-s2.0-37049071880
