| Description
| - The quinonoid ligand-bridged diruthenium compounds [(acac)2Ru(.mu.-L)Ru(acac)2 (acac- = acetylacetonato = 2,4-pentanedionato; L2 =2,5-dioxido-1,4-benzoquinone, 1; 3,6-dichloro-2,5-dioxido-1,4-benzoquinone, 2; 5,8-dioxido-1,4-naphthoquinone, 3; 2,3-dichloro-5,8-dioxido-1,4-naphthoquinone, 4; 1,5-dioxido-9,10-anthraquinone, 5; and 1,5-diimido-9,10-anthraquinone, 6) were prepared and characterized analytically. The simultaneous presence of highly redox-active quinonoid-bridging ligands and of two ruthenium centers capable of adopting the oxidation states +2, +3, and +4 creates a large variety of possible oxidation state combinations. Accordingly, the complexes 1–6 exhibit two reversible one-electron oxidation steps and at least two reversible reduction processes. While the first reduction steps are assigned to largely ligand-centered processes, the oxidation appears to involve metal–ligand delocalized molecular orbitals with variable degree of mixing.

- Dirutheniové komplexy s chinonoidním můstkem [(acac)2Ru(.mu.-L)Ru(acac)2 (acac- = acetylacetonato = 2,4-pentanedionato; L2 =2,5-dioxido-1,4-benzochinon, 1; 3,6-dichloro-2,5-dioxido-1,4-benzochinon, 2; 5,8-dioxido-1,4-naftochinon, 3; 2,3-dichloro-5,8-dioxido-1,4-naftochiinon, 4; 1,5-dioxido-9,10-antrachinon, 5; a 1,5-diimido-9,10-antrachinon, 6 ) byly připraveny a charakterizovány analyticky. Současná přítomnost vysoce redox-aktivních chinonoidních můstkových ligandů a dvou rutheniových center schopných přijmout oxidační stavy +2, +3, a +4 vytváří velkou rozmanitost možných kombinací oxidačních stavů. V důsledku toho komplexy 1-6 vykazují dva reverzibilní jednoelektronové oxidační kroky a přinejmenším dva reverzibilní redukční procesy. Zatímco první redukční stupně byly přiřazeny procesům lokalizovaným převážně na ligandy, oxidace zahrnuje molekulární orbitaly delokalizované mezi kovy a ligandy, s proměnnou mírou smíšení. (cs)
