| Sumario: | The complexes [N3P3(OC6H5)5OC6H4CH2CN.FeCl2]PF6 (<A HREF="#1">1</A>) and [N3P3(OC6H4CH2CN)6. (FeCl2)6](PF6)6 (<A HREF="#2">2</A>) have been syntethyzed by reaction of the corresponding cyclophosphazene ligands: N3P3(OC6H5)5OC6H4CH2CN (<A HREF="#3">3</A>) and N3P3(OC6H4CH2CN)6 (<A HREF="#4">4</A>) with FeCl3 in CH3OH as solvent and in presence of NH4PF6. The new compounds were characterized by elemental analysis and IR, UV-Visible and EPR spectroscopy as well as electrochemical methods. The hexametalladendrimers exhibits a six-electron reduction while that the monometalladendrimers exhibit a single one-electron reduction. The paramagnetic complexes exhibit strong EPR signals in solid as well as in CH2Cl2 solution. |
