Gold , phosphino complexes

Gold(111) complexes have also been prepared with mixed-donor ligands such as the phosphino thiolates PhP(C6H4SH)2 or P(C6H4SH)3, which give the dinudear...

Oxidative addition of halogens to the 1 2 complexes of bis(diphenyl-phosphino)methane or -propane with gold(I) chloride (11) forms the Au(II) complexes (12) (93). 

The crystal structures of the AuI/Fe11 complexes have been determined by X-ray diffraction methods showing a typical linear environment for the gold(I) center and none of them display intramolecular Au- Fe interactions (see Fig. 8). The phosphino derivative does not display intermolecular Au- -Au interactions either (the shortest gold-gold distance is 5.560 A), but the lattice shows F- -F (2.858 A) and F- -H (2.55 and 2.60 A) contacts. In contrast, ferrocenylpyridine complex molecules are associated into pairs across inversion centers via a weak intermolecular Au- -Au interaction of 3.301(2) A, similar to that observed in the case of the (thiophenylmethyl)diphenylpho-sphine derivative [ (C6F5)Au 2 p.-PPh2C(=S)N(H)Me described above (Au- -Au 3.2712(5) A).34...
