Organometallic Lewis Acids, IL [1] . – Bis(acyl)1‐Bridged Heterometallic Complexes of Rhenium, Molybdenum, Ruthenium, and Copper The reaction of the metalla‐β1‐diketonate complex [(OC) 4 1‐Re[–C(Me)O] 2 ][NMe 4 ] with various organometallic Lewis acids yields the bis(acyl)1‐bridged bimetallic complexes (OC) 4 ‐Re[–C(Me)O–] 2 Re(CO) 4 ( 1 ), (OC) 4 Re[–C(Me)O–] 2 MoCp(CO) 2 ( 2 ), (OC) 4 Re[–C(Me)O–] 2 Ru(η 3 1‐C 3 H 5 )(nbd) (nbdnorbor‐nadiene) ( 3 ), [(OC) 4 Re[–C(Me)O–] 2 Ru(PPh 3 ) 2 (CO) 2 ][BF 4 ] ( 4 ), and (OC) 4 Re[–C(Me)O–] 2 Cu[–O(Me)C–] 2 Re(CO) 4 ( 5 ), respectively. The structures of the compounds 1–5 have been determined by X‐ray diffraction. They show different conformations of the six‐membered ring Re[–C(Me)O–] 2 [M]. The molecular structure of complex 1 proves a “flipping” of the acyl ligands.
