“…Similar metal-gold separations have been found in other heterometallic complexes having bridging hydrides, e.g., 2.697 (1) and 2.673 (1) in [IrAu2(H)(PPh3)4(N03) ] BF4. 33 The Ir-P bond distances are unequal due to the different trans influence of the various coligands; thus, the longest value [2.354…”

“…Chaudret et al have recently reported the preparation and characterization of the NMR static, neutral complex [ (ij-C5Mes){(C6H 1i )3P}Ru^-H){ Au(PPh3}2] (6), but no X-ray data are available (Chart I).26c Pignolet et al reported the X-ray structure of [IrAu2(H)(PPh3)4(N03)]BF4 (7) without being able to precisely determine the bonding mode of the hydride ligand. 33 In fact, while NMR measurements were diagnostic for a terminal hydride stereochemistry, potential energy calculations based on the X-ray coordinates of the non-hydrogen atoms indicated that a bridging hydride may be nicely accommodated over one of the two iridium-gold bonds. Unfortunately, the hydride ligand could not be located by X-ray methods.…”

“…In striking contrast, neutral or cationic gold­(I) fragments form stable bridging compounds with a plethora of other transition-metal hydride complexes spanning the whole d block, including Nb, Mo, W, Cr, Mn, Re, , Ru, , Os, Ir, Rh, Pt, , Cu . In light of the Au + /H + isolobal relationship, the stabilization of such bimetallic structures has been generally ascribed to the occurrence of donor–acceptor interactions, or 3-center-2-electron (3c–2e) bonding, with different implied degrees of metal–metal bonding contribution.…”
