Abstract: NOVEL NEUTRAL IRON(II) ISOCYANIDE MALEONITRILE DITHIOLATE [Fe(S2C2(CN)(2))(t-BuNC)(4)] COMPOUND FeBr2 reacts with the S2C2(CN)(2)(2-) ion (1:1 ratio) in the presence of an excess of t-BuNC in THF to give the mixed ligand [Fe(S2C2(CN)(2))(t-BuNC)(4)] compound. This neutral product with a formal oxidation state of two for the iron atom was characterized by conductivity measurements, and, i.r., Mossbauer, C-13 and H-1 n.m.r. spectroscopy. There is a Fe-C pi back-donation strengthened towards isocyanide ligands, according to the data of C-13, H-1 n.m.r. and Mossbauer spectroscopy.
