| fussnote | The electrochemical behaviour of thio and phosphido complexes of iron(I): Fe"2XY(CO)"6""nL"n (X = Y = SR, PR"2 and X = SR, Y = PR"2, L = PR"3) has been studied on platinum and mercury electrodes, in organic solvent. These complexes are reduced in a two-electron irreversible process. A large difference is observed between their oxidation potentials on mercury and platinum electrodes; this is ascribed to the formation of a mercury complex in which mercury is inserted into the metalmetal bond. In oxidation on platinum electrodes, two mono-electronic waves are observed. The influece of the ligand basicity on the cathodic E"1"2 values is discussed. A parallel shift is observed between the E"1"2 and the IR ν(CO) of the totally symmetrical mode. Chemical oxidation of the complexes shows that the dications cannot be isolated, and leads to isolation of the following species: [FeP(CH"3)"2(CO)"3]"2AgNO"3, [FeSCH"3(CO)"2P(CH"3)"3]"2(NO"3)"2, {[FeSCH"3(CO)"2P(CH"3)"3]"2F} PF"6, where NO"3^- and F^- act as ligands. |
