| Popis: | AU 2 Cl 2 (μ-1,1′-bis(diphenylphosphino)ferrocene (dppf) reacts with Na[M(CO) 5 ] to give [AuM(CO) 5 ] 2 (μ-dppf) (M Re ( 1 ); M Mn ( 2 )) in 45% and 71% yields respectively. Both 1 and 2 represent pentametallic structures with a dppf metalloligand bridging between two heterometallic fragments which consist of AuM bonds. The X-ray photoelectron spectroscopic data suggested polarization of the Au δ+ Re δ- bonds in 1 . Contrary to 1 , (CO) 9 Re 2 (μ-dppf)AuCl ( 3 ), which is synthesized from Re 2 (CO) 9 (dppf- P ) and AuCl(Me 2 S) in 65% yield, shows binding energies typical of Au I and Re 0 . Reaction between Au 2 Cl 2 (μ-dppf) and K 2 Pd(CN) 4 resulted in no MM bond but ligand displacement to give Au 2 (CN) 2 (μ-dppf) ( 4 ) (yield, 8%) as the only isolable product. |
