Reactions of matrix-isolated iron atoms with dinitrogen

The results of a study carried out to better characterize the product formed in the co-condensation reaction of iron with N/sub 2/ with regard to both the metal and ligand stoichiometry are reported. Results of ir and Mossbauer spectral studies and of concentration variation studies are presented. All data support the conclusion that the complex is a monomeric species, most likely Fe(N)/sub 5/. No evidence is furnished to support beliefs that the structure of such compounds differs significantly from their Fe/CO analogues.
