Résumé
The ferrocenyl-containing diruthenium complexes [Ru-2(CO)(4)(mu(2)-eta(2)-OOCFc)(2)L-2] (Fc=ferrocenyl, fc=ferrocen-1,1'-diyl; 1: L=NC5H4-COOC6H4-OC10H21, 2: L=NC5H4-COOC6H4-OC16H33, 3: L=NC5H4-OOC-fc-C12H25) and [Ru-2(CO)(4)(mu(2)-eta(2)- OOC6H5)(2)(NC5H4-OOC-fc-C12H25)(2)] (4) have been synthesized from Ru-3(CO)(12), ferrocene carboxylic or benzoic acid and the corresponding pyridine derivative. The synthesis of the new pyridine derivative NC5H4-OOC-fc-C12H25 used for the preparation of 3 and 4 is also reported. Complexes 1-4 posses a so-called sawhorse structure consisting of the Ru-2(CO)(4) backbone and two bridging carboxylato ligands, while the coordination sphere around the ruthenium atoms is completed by the pyridine-derived ligands bonded in the axial positions. The electrochemical behavior of 1-4 and their known analogues [Ru(CO)(4)(mu(2)-eta(2)-OOCFc)(2)L-2] (5: L = NC5H5, 6: L = P(C6H5)(3), 7: L = NC5H4-OOCFc) has been studied by voltammetry on rotating disc electrode and by cyclic voltammetry.
