N2 - Reactions of the {AuC2R}n polymer (R = -C 6H4NO2, -C6H5, -C 6H4Ph, -C6H4OMe, -C 6H4NMe2, -C(OH)Me2, -C 6H10(OH)) with stoichiometric amount of 1,4-bis(diphenylphosphino)butane and Cu(I) ions afford the dicationic complexes of general formula [Au6Cu2(C2-R) 6(PPh2(CH2)4PPh2) 3](PF6)2. The compounds obtained (1-7) display common "rods-in-belt" structural motif with the "Cu 2{Au(C2R)2}3" central cluster core wrapped about by the {Au3(Ph2P(CH2) 4PPh2)3} belt. This structural pattern was revealed in solid state by X-ray crystallography and confirmed in solution using the NMR spectroscopy. The complexes 6 and 7 containing hydroxyl substituents in the alkynyl ligands demonstrate structural distortions due to hydrogen bonding inside the cluster core. All complexes studied exhibit intense phosphorescence in dichloromethane solution, the characteristics of which depend on donor ability of the alkynyl ligand substituents. Comparison of the emission wavelengths in 1-7 with those observed in the congeners based on the arom
