affords [FeII(Me2pipdt)3]2+ which is isolated as a tetrafluoroborate salt (5). The same cation is found in the polyiodide salt [FeII(Me2pipdt)3](I3)1.8(I)0.2 (6) obtained by reacting iron-metal powders with Me2pipdt and I2 mixtures. Through a similar reaction by using cobalt-metal powders, [CoIII(Me2pipdt)3]2(I3)2(I)4·2I2 (7) is obtained. Structural results show that in all these compounds the metal ions
