Abstract The Mössbauer effect spectra of structurally characterized molecular metal clusters provide a valuable reference point for the identification of surface generated species important in chemisorption and catalysis. The resulting hyperfine parameters may also aid structural elucidation and provide insight into the electronic environment of the individual iron sites. We have studied in detail the clusters Na2Cu6Fe4(CO)16, Na3Cu5Fe4(CO)16, and Na3Cu3Fe3(CO)12, and several related compounds. The results indicate that the Mössbauer effect isomer shifts at 78K, which vary from −0.123 to −0.035mm/s, are very sensitive to the bonding in the molecular cluster.
