Gold I Complexes with Polydentate Ligands

Another important class of bidentate ligands in gold chemistry are those composed of sulfur donor ligands such as dithiocarbamates, dithiolates, dithiocarboxylates, dithiophosphinates, dithiophosphates, and so on. The complexes prepared with these ligands are generally of the type Au2(p.-SS)(PR3)2] + or Au2(p-SS)(p-PP)] [153-155], [Au2(p-SS)2f [156, 157] or Au3( i-SS)2(PPh3)2 [158]. All these 

Other oligomeric complexes are obtained with nitrogen donor ligands including amides, such as [Au4 NSiMe3)3 4] [226], or formamidates such as [Au4 (NPh)2CH 4] [227], triazenides, such as [Au4 (NPh)2N 4] [228], or pyrazolates, such as the trinuclear species commented above or the hexanuclear [Au6(2-5-Ph2pz)6] [229].
