The complexes [R2ClAuPPh2CH2PPh2CH 2COOMe]ClO4 and [R2ClAuSPPh2CH2PPh2CH 2COOMe]ClO4 (R = C6F5) can be deprotonated with AgClO4, Na2CO3, or NaH to synthesize four-, five-, or six-membered auracycles: [R2AuSPPh2CHPPh2CH2COOMe]ClO 4, [R2AuPPh2CHPPh2CHCOOMe], [R2-AuPPh2CH2PPh2CHCOOMe]ClO 4, or [R2AuSPPh2CHPPh2CHCOOMe]. The methanide C atom in these neutral complexes is a nucleophile and can be used as donor atom to form homodinuclear complexes [R2Au{SPPh2(AuX)PPh2CHCOOMe}] (X = C6F5) or [R2Au{PPh2CH(AuX)PPh2CHCOOMe}] (X = Cl, C6F5) or heterodinuclear complexes [R2Au{PPh2CH(AgPPh3)PPh 2CHCOOMe}]ClO4. The structure of [(C6F5)2Au{PPh2CH(AuC 6F5)PPh2CHCOOMe}] has been solved by X-ray crystallography. It crystallizes in space group P1 with a = 12.719 (5) ?, b = 12.830 (5) ?, c = 17.918 (7) ?, α = 70.67 (3)°, β = 76.11 (3)°, γ = 72.07 (3)°, and Z = 2.
