摘要：

Polypyridylruthenium(II) complexes with redox-active, structurally isomeric catechol or hydroquinone units were newly prepared to examine the structure-stability relationships in the redox-active sites. A marked difference based on the structure of the active site was confirmed with respect to the formation of the oxidized forms, i.e. the quinone complexes: only the para-isomer was completely converted into the corresponding quinone form. The conversion of Ru-II to Ru-III was not observed. Redox-mediated interconversion between the hydroquinone and para-quinone units is also reported.
