A decanuclear ruthenium(II)–polypyridine complex: synthesis, absorption spectrum, luminescence and electrochemical behaviour

Abstract

A novel oligonuclear Ru(II)–polypyridine complex, Ru{(µ-2,3-dpp)Ru[(µ-2,3-dpp)Ru(bpy)2]2}3(PF6)201, where dpp = bis(2-pyridyl)pyrazine and bpy = 2,2′ bipyridine, has been prepared from the reaction of a Ru(2,3-dpp)32+ core 2 with three Ru[(µ-2,3-dpp)Ru(bpy)2]2Cl24+ units; 1 shows a very intense absorption band at 541 nm (ε= 1.25 × 105 dm3 mol–1 cm–1), room temperature luminescence (λmax= 809 nm, τ= 55 ns, Φ= 10–3), and independent one-electron oxidation of the six peripheral Ru2+ ions at +1.43 V vs. saturated calomel electrode (SCE).
