Gold–Heterometal Interactions and Bonds

“…For most of them the metallic frameworks can be derived from a Pt-centered Au 12 icosahedron by removing seven [41], six [555,556], four [556,558], three [548,[559][560][561], or two [556] vertices. Clusters with similar cores in which up to three gold atoms are replaced by atoms of another metal have also been reported, for example, Pt-Au 5 Pt 2 [550], Pt-Au 6 Hg [42], Pt-Au 5 Hg 2 [41], Pt-Au 8 Ag [556,562,563], Pt-Au 8 Ag 2 [563], Pt-Au 8 Cu [556,564] and Pt-Au 8 Cu 2 [564].…”

Cluster Complexes with Bonds Between Transition Elements and Copper, Silver and Gold

“…For example, the formal replacement of a CO group by a C 2 Bu l ligand in the cluster cation [Au 6 Pt(CO)(PPh 3 ) 7 ] 2+ changes the metal core structure from two Au 4 Pt trigonal bipyramidal units fused together by sharing a common face to two Au 4 Pt square-based pyramidal fragments linked together via a common face. 234 ' In the case of the compounds [Au 4 Fe 2 {u-Ph2(CH2) w PPh2}2(CO) 8 ], the two bidentate diphosphine ligands link together two well-separated trigonal planar Au 2 Fe units when n = 2 (Table 14), whereas a metal core structure consisting of an Au 4 'butterfly' with two Fe(CO) 4 units bridging opposite Au-Au edges of the two 'wings' is adopted when n = 1 (Table 19). 196 Also, most of the clusters listed in Table 1 9 have metal skeletons which are stereochemically nonrigid in solution (see Section 5.2.…”
