Abstract A series of gold(I) acetylide complexes, Cy3PAuC CC6H4-C(O)R-4 (R H (1), Me (2), OMe (3), NH2 (4)) (Cy3P = tricyclohexylphosphine), have been synthesized and characterized. The crystal structures of Cy3PAuC CC6H4-C(O)H-4 (1) and Cy3PAuC CC6H4-C(O)NH2-4 (4) were determined by X-ray diffraction. The photophysical properties of complexes 1–4 have been studied. Complexes 1–4 show luminescence both in the solid state and in acetonitrile solution at 298 K, and their emission energies are in the order: 4 > 3 > 2 > 1.
