Abstract
The reaction of [Ru(OH2)2(RaaiR/)2]2+ [RaaiR/=1-alkyl-2-(arylazo)imidazole, p-R-C6H4-N=N-C3H2NN(1)-R/, R=OMe (2), R/=Me (a), Et (b), with 8-quinolinol (HQ) in acetone solution followed by the addition of NH4PF6 has afforded violet coloured mixed ligand complexes of the composition [Ru(Q)(RaaiR/)2](PF6). The structure of [Ru(Q)(OMeaaiMe)2](PF6) (2a) has been confirmed by x-ray diffraction studies. The solution electronic spectra exhibit a strong MLCT band at 560-580 nm in MeCN. Cyclic voltammograme 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.
