Title: The Behavior of the Ru-bda Water Oxidation Catalysts at Low Oxidation States

Abstract

The Ru complex [Ru II(bda-κ-N 2O 2)(N-NH 2) 2], 1, (bda 2- = (2,2'-bipyridine)-6,6'-dicarboxylate; N-NH 2 = 4-(pyridin-4-yl)aniline) is used as a synthetic intermediate to prepare Ru-bda complexes that contain the NO +, acetonitrile (MeCN) or H 2O ligands at oxidation states II and III. Complex 1 reacts with excess NO + to form a Ru complex where the aryl amine ligands N-NH 2 in 1 are transformed into diazonium salts (N-N 2 + = 4-(pyridin-4-yl)benzenediazonium)) together with the formation of a new Ru-NO group at the equatorial zone, to generate [Ru II(bda-κ-N 2O)(NO)(N-N 2) 2] 3+, 2 3+. Similarly, complex 1 can also react with a coordinating solvent, such as MeCN, at room temperature leading to complex [Ru II(bda-κ-N 2O)(MeCN)(N-NH 2) 2], 3. Finally in acidic aqueous solutions solvent water coordinates the Ru center forming {[Ru II(bda-κ-(NO) 3)(H 2O)(N-NH 3) 2](H 2O) n} 2+, 4 2+, that is strongly hydrogen bonded with additional water molecules at the second coordination sphere. We have additionally characterized the one electron oxidized complex {[Ru III(bda-κ-(NO) 3.5)(H 2O)(N-NH 3) 2](H 2O) n} 3+, 5 3+. The coordination mode of the complexes has been studied both in the solid state and in solution through single-crystalmore » XRD, X-ray absorption spectroscopy, variable-temperature NMR and DFT calculations. While the κ-N 2O is the main coordination mode for 2 3+ and 3, an equilibrium that involves isomers with κ-N 2O and κ-NO 2 coordination modes and neighboring hydrogen bonded water molecules is observed for 4 2+ and 5 3+.« less
