The topology of the centered gold clusters can be considered to be either spherical or toroidal depending on whether the center gold atom uses a nine-orbital spherical sp d ... 

The following features of centered gold clusters make their systematics very different from other metal cluster compounds such as metal carbonyl clusters ...

Layer-by-layer Ru3 cluster-based multilayers were fabricated onto preorganized self-assembled monolayer gold electrode surfaces by Abe et al. [15], in which [Ru3(q3-0)( i-0Ac)6(4,4/-bpy)2(C0)] was utilized as the synthetic precursor. The stepwise connection of oxo-centered triruthenium cluster units onto the gold electrode surface is a feasible approach for construction of Ru3 cluster-based oligomers on a solid surface, in which the bridging ligand 4,4 -bipyridine appears to mediate weak cluster-cluster electronic interaction between the Ru3 cluster centers.

We also compare our results to XPS data on bulk gold and on the smaller centered clustercompound Au 11L7X3 (with X = Cl or I) [74]. A comparison is also made to XPS results obtained on bare gold clusters deposited on poorly conducting substrates [75, 76]. This gives still more support to the idea of the metallic bonding of the Aujj clusters. 

The rich-gold clusters [ (Ph3P)Au 7Co(CO)2](PF6)2 343 [435], [ (Ph3P)Au 7Rh (C0)2](N03)2 344 [454] and [ (Ph3P)Au 6(ClAu)2Rh(dmpi)2](PF6) 345 [454, 458] may be described as derivatives of a metal-centered Au12 icosahedron formed by removing five and seven vertices from the icosahedral cage. 

Several new polynuclear gold clusters have been obtained (37, 38, 77), and the structures of an AUg and another AUjj cluster have been determined (37, 39). Their basic atom arrangements [75] and [76] can be derived from centered icosahedra by removing certain vertices.
