This contribution describes an updated synthetic route along with full characterization of [{CpFe}2-p-Ph'] with p-Ph 3,4,. The complex reported here was characterized by 1 H and 13 C NMR, elemental analysis, the X-ray crystal structure, and Mössbauer spectroscopy. From the crystallographic analysis, it was found that both {CpFe} fragments are coordinated to opposite sites of the p-Ph' ligand. In addition, the analysis through of 1 H and 13 C NMR spectroscopy, confirm that the synthesis and yield of just one isomer of this compound.
