Resumen

The reaction of [Au(tht)2]ClO4 or NBu4[Au(acac)2] with 2 equiv of [Au(C6F5)3PPh2CH 2-PPh2] affords the cationic [{Au(C6F5)3PPh2CH 2PPh2}2Au]ClO4 (1) or anionic complex NBu4[{Au(C6F5)3PPh 2CHPPh2}2Au] (2), respectively, in high yield. The methanide complex 2 can displace tetrahydrothiophene from [AuX(tht)] to give the pentanuclear NBu4[{Au(C6F5)3-PPh 2CH(AuX)PPh2}2Au] (X = Cl, C6F5). The heptanuclear [{Au(C6F5)3PPh2C(AuPPh 3)2-PPh2}2Au]ClO4 is obtained by reaction of 1 with [Au(acac)PPh3] (molar ratio 1:4). The structure of 2 has been determined by a single-crystal X-ray diffraction study. It crystallizes in the space group P1 with a = 14.213(4) Å, b = 16.067(4) Å, c = 23.840(6) Å, α = 88.60(2)°, β = 89.27(2)°, γ = 71.23(2)°, Z = 2, and T = -100°C. It does not display gold-gold interactions. © 1995 American Chemical Society.
