Electrochemical Reduction of Some Tris(β-diketonato)ruthenium(III) Complexes in Acetonitrile and Interaction of the Reduced Anions with Lithium and Sodium Ions

In tetraethylammonium perchlorate-acetonitrile solution, (R1,R3= -CH3, -CF3, -C6H5, -C(CH3)3; R2= -H, -C6H5) was reversibly reduced at a dropping mercury electrode to the corresponding univalent anion. A linear relationship was found between the half-wave potential and the sum of the Hammett constants of the substituents of ligands. In some cases, the polarogram and the cyclic voltammogram were shifted to more positive potentials in the presence of lithium or sodium ions. This effect was explained quantitatively by the two-step association between the reduction product, -, and alkali metal ions. The association constants were calculated.The K2 values were appreciable and the K1 values were much larger than expected for a simple electrostatic interaction. Furthermore, the K1 values were linearly related to the sum of the Hammett constants of the substituents of the ligands. These results suggest the importance of the local charge distribution on the complex anions. In the presence of lithium ion, - forms Li which is insoluble in acetonitrile.

Volatile β-diketonato complexes of ruthenium, palladium and platinum preparation and thermal characterization

Ruthenium, palladium and platinum complexes of 2,2,6,6-tetramethyl-3,5-heptanedione (thd) and ruthenium tris acetylacetonate (acac) were synthetized and studied with TG, DTA, DSC and MS methods. Thermal properties of ruthenocene were also studied. The pla
