Summary of "A Di-ruthenium Complex of a N-Pyridyl-o-Aminophenol Derivative: A Route to Mixed Valency."

A N-pyridyl-o-aminophenol derivative that stabilizes mixed-valence states of ruthenium ion is disclosed. A diruthenium complex, [(LIQ0)Ru2Cl5]•MeOH (1•MeOH) was successfully isolated, where LIQ0 is the o-iminobenzoquinone form of 2-((3-nitropyridin-2-yl)amino)phenol (LAPH2). In 1, LIQ0 towards one ruthenium centre is a NO-donor redox noninnocent, while towards another ruthenium it is a pyridine donor redox innocent ligand. 1 is a diruthenium (II, III) mixed valence complex, [RuII(LIQ0)(μ-Cl)2RuIII], with a minor contribution of diruthenium (III, III) state, [RuIII(LISQ●-)(μ-Cl)2RuIII] where LISQ●- is the o-iminobenzosemiquinonate anion radical form of the ligand. 1- and 1+ are respectively diruthenium (II, II), [RuII(LIQ0)(μ-Cl)2RuII], and diruthenium (III, III), [RuIII(LIQ0)(μ-Cl)2RuIII], complexes of LIQ0. 12- is a diruthenium (II, II) complex of o-iminobenzosemiquinonate anion radical (LISQ●-), [RuII(LISQ●-)(μ-Cl)2RuII] with a minor contribution of diruthenium (III, II) form, [RuIII(LAP2-)(μ-Cl)2RuII]. 12+ is a diruthenium (III, IV) mixed valance complex of LIQ0, [RuIII(LIQ0)(μ-Cl)2RuIV]. 1 and 12+ exhibit inter valence charge transfer transitions at 1300 and 1370 nm.
