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

The novel iron-sulfur cluster dimer {bis[(1,1'-dithiolatoferrocene-mu-sulfi do-ferrate(III)]}(2-) is Prepared as the tetrapropylammonium salt in a one- pot synthesis from 1,1'-trithiaferrocenophane, FeCl3, and (BuS-)-Bu-t. The X-ray crystallography, electronic spectroscopy, electrochemistry, and magne tic susceptibility of this complex are reported and compared and contrasted to previously prepared iron-sulfur dimer complexes with organic thiolate l igands.
