Although most of the structurally characterized gold clusters are phosphine-based systems, in recent years some studies have focused on the synthesis of gold clusters with other stabilizers coexisting with phosphines such as thiols, arsines and boranes. Certain heteroleptic gold clusters stabilized with these ligands and arylphosphines in the same molecule have been structurally characterized. [Pg.136]

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). [Pg.349]

The formation-growth of gold clusters was monitored by UV-Vis spectroscopy, by looking at the very intensive surface plasmon absorption characterizing nano-sized gold. Optical spectra were recorded at different reaction... [Pg.161]
