Synthesis and characterization of the dinuclear iron–sulfur cluster {bis[(1,1′-dithiolatoferrocene-μ-sulfido-ferrate(III)]}2−

The novel iron–sulfur cluster dimer {bis[(1,1′-dithiolatoferrocene-μ-sulfido-ferrate(III)]}2− is prepared as the tetrapropylammonium salt in a one-pot synthesis from 1,1′-trithiaferrocenophane, FeCl3, and tBuS−. The X-ray crystallography, electronic spectroscopy, electrochemistry, and magnetic susceptibility of this complex are reported and compared and contrasted to previously prepared iron–sulfur dimer complexes with organic thiolate ligands.
