Abstract

The reaction of [Ru(OH2)2 (RaaiR')]2+ [RaaiR' = 1-alkyl-2-(arylazo)imidazole, p-R-C6H4-N = N-C3H2-NN(1)-R', R = H (1), Me (2), Cl (3); R' = Me (a), Et (b), CH2Ph (c)] with 8-quinolinol (HQ) in acetone solution followed by the addition of NH4PF6 afforded violet, mixed ligand complexes of composition [Ru(Q)(RaaiR')2](PF6). The structure of [Ru(Q)(MeaaiMe)2](PF6) (2a) has been confirmed by X-ray diffraction studies.Solution electronic spectra exhibit a strong MLCT band at 560-580 nm in MeCN. Cyclic voltammogrames show a Ru(III)/Ru(II)couple at 1.0-1.1 V versus SCE along with three successive ligand reductions. The electronic properties are correlated with EHMO results.
