“…A structural diversity of heterodimetallic and -trimetallic cores was observed for the pentanuclear species containing Au-Fe [296][297][298][299][300][301][302][303][304][305][306][307][308][309], Au-Ru [267,272,[310][311][312][313][314][315][316][317][318][319][320][321][322][323][324][325] and Au-Os [326][327][328][329][330][331][332][333][334][335]. A (Ph 3 P)Au unit can bridge in a m 3 -fashion a face of a tetrahedral heterodimetallic (Fe 2 Ir 2 , Fe 2 Rh 2 , Ru 2 Rh 2 , Ru 3 Rh, Ru 3 Co) core [296,297,310,311,315] [311]…”

“…For clusters with an Au 2 M 3 core (M ¼ Fe [298][299][300], Ru [267,314,[316][317][318]) the distorted trigonal bipyramidal geometry can be considered as arising from a butterfly AuM 3 fragment m 4 -bridged by a second Au atom, for example [(Ph 3 P)Au] 2 An edge-bridged (R 3 P)Au unit was also found in pentanuclear clusters in which all four metal atoms of the butterfly tetrametallic core are coordinated by a carbon [301,302] or a nitrogen [303,321] atom. The gold atom bridges the hinge Fe-Fe or Ru-Ru bond, for example, in neutral (Et 3 P)AuFe 4 (m 4 -COMe)(CO) 12 [334,335].…”
