Acetylenephosphino gold(I) derivatives: Structure, reactivity and luminescence properties

We have synthesised the acetylenephosphino gold(I) derivatives, AuX(PPh2CCH) (X = Cl, Br, I, C6F5). X-Ray diffraction studies show that the chloro derivative is a dimer connected by two short hydrogen bonds from the acetylenic hydrogen to chlorine, whilst the iodo derivative is also a dime because of a gold-gold interaction of 3.0625(9) A. The crystal structure of the pentafluorophenyl derivative shows the presence of intermolecular hydrogen bonds Au...H (3.07 A, 143°), also from the acetylenic hydrogen, which link the molecules into claims. The possibility of preparing alkynyl derivatives has been investigated but only complex [Au(C6F5)(PPh2CC)Au(C6 F5)]-[N(PPh3)2] 6 has been obtained in a pure state. Complex 6 luminesces at room temperature in the solid state, and all the complexes are luminescent at 77 K with excitation maxima in the range 292-335 nm and emission maxima between 445 and 533 nm.
