  Synthesis, spectral characterisation, redox studies of isomeric dichloro-bis-[1-alkyl-2-(naphthyl-(α/β)-azo)imidazole]ruthenium(II). Single crystal X-ray structure of blue-green dichloro-bis-[1-ethyl-2-(naphthyl-α-azo)imidazole] ruthenium(II)

  摘要：

  Ruthenium(II) complexes with 1-alkyl-2-(naphthyl-(alpha/beta)-azo)imidazoles (alpha/beta -NaiR), where R = Me, Et and Bz have been synthesised. Two isomers, blue-green, tuans-cis-cis and blue, cis-rrans-cis of the composition Ru(NaiR)(2)Cl-2, are chromatographically separated. With reference to the pairs Cl, N(imidazole) and N(azo). the blue-green isomer is assigned to a trans-cis-ris configuration and the blue, isomer is assigned to a cis-trans-cis configuration. They are characterized by IR and H-1 NMR data. The structure of the blue-green complex, Ru( alpha -NaiEt)(2)Cl-2 has been determined by X-ray crystallography and the trans-cis-cis configuration has been confirmed. The complexes exhibit t(2)(Ru)--> pi* (ligand) MLCT transitions in the visible region. Cyclic voltammetry shows a Ru(III)/Ru(II) couple for the blue-green isomer at 0.4-0.5 V and the blue complexes at 0.5-0.6 V versus SCE, as well as multiple azo reductions.
