Notes:
The reaction of diphenyl(trimethylsilylmethyl)phosphane with [AuCl(tht)] affords the gold(I) complexes [AuCl(PPh2-CH2SiMe3)] (1) or [Au(PPh2CH2SiMe3)2]Cl (2). An X-ray study of 1 does not reveal any Au···Au interaction. Treatment of [Au(tht)2](CF3SO3) or [Au(tht)(PPh3)](CF3SO3) with diphenyl(trimethylsilylmethyl)phosphane results in the displacement of the thioether ligands to give the ionic complexes [Au(PPh2CH2SiMe3)2](CF3SO3) (3) or [Au(PPh2-CH2SiMe3)(PPh3)](CF3SO3) (4), the latter mixed with the symmetrical derivatives [Au(PPh2R)2](CF3SO3) (R = Ph, CH2-SiMe3). The molecular structure of complex 3 has been established by X-ray diffraction and shows an antiperiplanar arrangement of the two PR2R rotors in the solid state. The reaction of the phosphane ligand with [Au2{μ-(CH2)2-PPh2}2(tht)2](ClO4)2affords the dinuclear gold(II) complex [Au2{μ-(CH2)2PPh2}2(PPh2CH2SiMe3)2](ClO4)2 (5).
