✦ Synopsis

Gold(I) / Gold(II) / Diphenyl(trimethylsilylmethyl)phosphane / Ligand effects The reaction of diphenyl(trimethylsilylmethyl)phosphane CH 2 SiMe 3 )(PPh 3 )](CF 3 SO 3 ) (4), the latter mixed with the symmetrical derivatives [Au(PPh 2 R) 2 ](CF 3 SO 3 ) (R = Ph, CH 2 -with [AuCl(tht)] affords the gold(I) complexes [AuCl(PPh 2 -CH 2 SiMe 3 )] (1) or [Au(PPh 2 CH 2 SiMe 3 ) 2 ]Cl (2). An X-ray SiMe 3 ). The molecular structure of complex 3 has been established by X-ray diffraction and shows an antiperiplanar study of 1 does not reveal any Au•••Au interaction. Treatment of [Au(tht) 2 ](CF 3 SO 3 ) or [Au(tht)(PPh 3 )](CF 3 SO 3 ) with arrangement of the two PR 2 RЈ rotors in the solid state. The reaction of the phosphane ligand with [Au 2 {µ-(CH 2 ) 2 -diphenyl(trimethylsilylmethyl)phosphane results in the displacement of the thioether ligands to give the ionic PPh 2 } 2 (tht) 2 ](ClO 4 ) 2 affords the dinuclear gold(II) complex [Au 2 {µ-(CH 2 ) 2 PPh 2 } 2 (PPh 2 CH 2 SiMe 3 ) 2 ](ClO 4 ) 2 (5). complexes [Au(PPh 2 CH 2 SiMe 3 ) 2 ](CF 3 SO 3 ) (3) or [Au(PPh 2 -
