Diferrocenyl disuMide was synthesized by the reduction of ferrocenesulfonyl chloride using aluminum iodide as a reducing reagent. The structure was characterized by elemental analysis, IR, 'H NMR and 13C NMR spectra. Crystal structure was determined by X-ray diffraction analysis. The crystal data belong to monoclinic space group with unit cell dimensions a =0.61881 (4) nm, b = 1.03231(9) nm, c = 1.39056(11) nm, β= 94.179(3)°, V = 0.85593(12) nm~3, D-c = 1.628 g/cm~3, μ= 1. 870 mm~-1, F(000)=444, Z =2, R-1 =0.027 and wR-2 = 0.0678.
