Ruthenium and osmium complexes of N,O chelators: Syntheses, oxidation levels, and distortion parameters

The N,O ligands concerned are HQ = 2-R-8-quinolinol (R = H, Me) and HL = N-arylsalicylaldimine, p-RC6H4N=CHC6H4OH (R = H, Me, OMe, CO2Et, Cl). The trivalent complexes synthesized are MQ3 (3 (M = Ru) and 8 (M = Os)), RuL3 (4), and [Et4N][OsX2Q2] (7, X = Cl, Br), and the quadrivalent species are [RuL3]PF6 (5), [OsQ3]ClO4 (9), and OsX2Q2 (6). Species 3 and 4 are obtained by the reaction of ligands with ruthenium trichloride and tris(acetylacetonate), respectively; 5 is electrosynthesized. The reaction of HQ with diammonium hexahaloosmate affords 6, which on further reaction with HQ furnishes 8. The syntheses of 7 and 9 are respectively achieved by reduction (hydrazine hydrate) of 6 and oxidation (cerium(IV)) of 8. On the basis of IR data, doping experiments, electrochemical behavior, and steric considerations, it is concluded that the tris complexes have meridional MN3O3 coordination spheres while 6 and 7 have the MX2N2O2 sphere in a trans-trans-trans geometry. All complexes display two cyclic voltammetric responses due to M(IV)/M(III) and M(III)/M(II) couples, and in the case of 8 a third couple corresponding to a higher level of oxidation is also observed. The formal potentials of the type 4 complexes linearly correlate with the Hammett constant of the R substituent. The trivalent complexes are one-electron paramagnets (idealized t2g5) and display characteristic rhombic EPR spectra. Two ligand field transitions within the three Kramers doublets have been identified in the near-IR region (-1). The g components are assigned on this basis, affording values of axial (Δ) and rhombic (V) distortion parameters. The complexes generally have large distortions, and values of Δ and V span the ranges 4000-6000 and 500-2000 cm-1, respectively. The RuL3 complexes are more distorted than the RuQ3 species.
