Abstract

The interest in the synthesis and reactivity of organometallic compounds which have two or more different metals in the same molecule has grown in recent years, due to the new chemical properties that they can present. In this work, we report the Mössbauer characterization of dppfFe(CO)3 and two novel compounds, dppfFe(NO)2 and [dppfCo(NO)2]+[SbF6], where dppf =1,1′-bis(diphenylphosphino)ferrocene. The complexes were also characterized by IR and31P NMR. The Mössbauer parameters of the dppfFe(NO)2 and dppfFe(CO)3, show two iron sites in the same proportions while for [dppfCo(NO)2+[SbF6] only one site was observed.
