Abstract: NOVEL NEUTRAL IRON(II) ISOCYANIDE MALEONITRILE DITHIOLATE [Fe(S 2C2(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., Mössbauer, 13C and 1H n.m.r. spectroscopy. There is a Fe-C π back-donation strengthened towards isocyanide ligands, according to the data of 13C, 1H n.m.r. and Mössbauer spectroscopy.
