Synthesis, structure and electrochemical properties of a group of ruthenium(III) complexes of N-(aryl)picolinamide

Reaction of N-(aryl)picolinamide (HL-R; R = OCH3, CH 3, H, Cl and NO2) with ruthenium trichloride or [Ru(DMSO)4Cl2] in refluxing 2-methoxyethanol in the presence of a base (NEt3) affords tris complexes of the type [Ru(L-R)3]. The structure of the [Ru(L-OCH3)3] complex has been determined by X-ray crystallography. In these complexes the amide ligands are coordinated to the metal center as monoanionic bidentate N,N-donors. All the [Ru(L-R)3] complexes are one-electron paramagnetic and show rhombic ESR spectra at 77 K. They also show intense LMCT transitions in the visible region. Cyclic voltammetry on all the complexes shows a ruthenium(III)/ruthenium(IV) oxidation within the range of 0.89 to 1.21 V vs. SCE and a ruthenium(III)/ruthenium(II) reduction within the range of -0.22 to -0.41 V vs. SCE. Representative one-electron oxidized and reduced complexes, viz. [RuIV(L-H)3]+ and [RuII(L-H) 3]-, respectively, have also been generated in solution and characterized spectroscopically as well as electrochemically.
