Abstract : EXAFS spectroscopy has been used in order to characterize in solution the structure of dinitrosyl iron-cobalt cationic complexes catalysing the polymerisation of olefins. EXAFS spectra were also recorded on the inactive precursors of these systems and on relevant model compounds : FeNO2PΦ3Cl, FeNO2PΦ32. For the cationic iron species, the results are quite consistent with a trigonal bipyramidal coordination of iron implying three non equivalent solvent molecules. In this system as in its precursor, the nitrosyl groups are found slightly bent.
