Gold heteronuclear clusters

A number of examples of gold heteronuclear cluster compounds containing AuX fragments, where X is a ligand other than phosphine, have also been synthesized. An interesting example is provided by the compound [AuIr3H6(N03)(dppe)3]+ (71), prepared by the reaction... 

Intermolecular dynamic processes are, in general, less common for gold heteronuclear cluster compounds. An example of such behavior in solution is provided by the compounds [(Ph3PAu)(p.-H)M(CO)5] (M = Cr, Mo, W) and [(Ph3PAu)(/ti-H)W(CO)4 P(OMe3) ] (32). The 31P 1H NMR spectra of these species are sharp singlets that shift appreciably... 

H NMR spectroscopy has been used extensively in the characterization of gold heteronuclear cluster compounds that possess hydride ligands. For example, Fig. 12 illustrates the hydride region of the H NMR spectrum of [Au4Rh(H)2 P(0-i-C3H7)3 2(PPh3)4]+ (155).
