A family of ferrocene-rich Mn7, Mn8 and Mn13 clusters

The use of ferrocene-1,1′-dicarboxylic acid (fdcH2) in Mn cluster chemistry has led to a family of ferrocene-rich Mn7, Mn8 and Mn13 clusters. The complexes are all mixed-valence. Solid-state DC and AC magnetic susceptibility studies have established the Mn7, Mn8 and Mn13 complexes to possess S = 2, 5 and 9/2 ground states, respectively.

The reactions of ferrocene-1,1′-dicarboxylic acid with Mn reagents have led to the preparation of Mn7, Mn8 and Mn13 clusters. The crystal structures and magnetic properties of these complexes are reported, which establishes that they possess S = 2, 5 and 9/2, respectively.Figure optionsDownload as PowerPoint slide
