Abstract
The reaction of the metalla-beta-diketonate complex [(OC)4-Re[-C(Me)O] 2][NMe4] With various organometallic Lewis acids yields the bis(acyl)- bridged bimetallic complexes (OC)4-Re[-C(Me)O-]2Re(CO)4 (1), (OC)4Re[- C(Me)O-]2MoCp(CO)2 (2), (OC)4Re[-C(Me)O-]2Ru(eta3-C3H5)(nbd) (nbd = no rbornadiene) (3), [(OC)4Re[-C(Me)O-]2Ru(PPh3)2(CO)2][BF4] (4), and (OC )4Re[-C(Me)O-]2Cu[-O(Me)C-]2Re(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.
