The temporal diffraction–difference approach of the ultrafast electron diffraction (UED) technique was used to determine the molecular structure of the transient [Fe(CO) 4 ] (see picture) formed during the elimination of CO ligands from [Fe(CO) 5 ]. The results clearly show that the major product, up to 200 ps, is the transient [Fe(CO) 4 ] which is formed in the 1 A 1 state, rather than the ground 3 B 2 state.
