Resumen

The reaction of CpFe(dppe)I with Ph2P (CH2)n PPh2 (n = 1, dppm; n = 2, dppe; n = 3, dppp; n = 4 dppb) in the presence of NH4PF6 afforded the novel mononuclear complexes [CpFe(dppe) (η1-dppm)]PF6 (1) and [CpFe(dppe) (η1-dppe)]PF6(2) when n = 1 or 2 or the binuclear [CpFe (dppe)-PPh2(CH2)2 PPh2-CpFe (dppp)] (PF6)2 (3) and [CpFe (dppe) PPh2(CH)2PPh2-CpFe (dppb)] (PF6)2 (4) when n = 3 or 4. These two bimetallic complexes present two slightly different sites caused by the two different chelate diphosphines linked to the iron atoms and evidenced by 31P-NMR spectroscopy. The two metallic fragments however could not be distinguished by cyclic voltammetry.
