Abstract
The i.r. spectrum of Fe2(CO)9(D3h) in matrices at 20 K is reported. Irradiation with u.v. light very rapidly produces spectral changes; annealing the matrix to 30 K leads to further changes and prolonged photolysis gives a final spectrum which is unaffected by subsequent annealing. These changes are attributed to the formation of both bridged and unbridged forms of Fe2(CO)8 and the bonding in this system is briefly discussed. There is evidence for the formation of nitrogen-containing carbonyl species during photolysis in nitrogen matrices.Keywords
