ResumoHeterobimetallic Complexes of the Boron and Aluminum Containing 2-(Dimethylaminomethyl)ferrocenyl Ligands: Syntheses, Characteristics and Structures The organometal derivatives (FcN)BCl2 (1), (FcN)2AlX [X = Br (2), I (3)] are formed at metathesis reactions of the anhydrous metal halides MX3 (M = B, X = Cl; M = Al, X = Br, I) with 2-(dimethylaminomethyl)ferrocenyl lithium, (FcN)Li. In contrary donor-acceptor complexes of the formula L → BX′3 [X′ = C6H5CH2 (4), Cl (5), Br (6), I (7)] are formed at metalation reactions of dimethylaminomethylferrocene (L, FcNH) and BX′3.The crystal structures of 1-3 and 5 could be proved by single crystal x-ray determinations. An intervalent electron transfer was determined by 57Fe-Mössbauer spectroscopy at 1-7. Cyclic voltammetric measurement was carried out at complex 4.
