Zusammenfassung

The gold (I) complexes [Au2 (S-S) (AsPh3) ] n (S-S = S2C6H4, S2C6H3CH3) react with (Ph2P (CH2) nPPh2) (n = 1, dppm; 2, dppe) affording [Au2 (S-S) (dppe) ] (1-2) or [Au4 (S-S)2 (dppm)2] (3, 4) . The gold (III) derivative [Au (C6F5) (S-S) (AsPh3) ] reacts with dppe giving rise to [{Au (C6F5) (S-S) }2 (μ-dppe) ] (5, 6) or with dppm affording [Au (C6F5) (S-S) dppm] (7, 8) . Complexes 7, 8 further react with the gold (I) compounds [AuX (tht) ] (X = Cl, C6F5) giving after substitution of the tetrahydrothiophene group, [Au2 (μ-dppm) (C6F5) X (S-S) ] (9, 10) . The crystal structure of [Au2 (μ-dppm) (C6F5)2(S2C6H 4) ] (10) has been established by X-ray diffraction and shows a linear Au (I) atom, bonded to a C6F5 group and a phosphorus of the dppm, which then bridges via the other phosphorus to a square planar Au (III) atom, which also carries a C6F5 group and a chelating dithiolate.
