A Ru2II,III diphosphonato complex with a metal–metal bond for water oxidation

Unlike [Ru2(μ-O2CCH3)4], the structurally analogous water-soluble Ru2II,III diphosphonato complex K3[Ru2(hedp)2(H2O)2] (K3·1) is only involved in stoichiometric water oxidation with a maximum 67% O2 yield under CAN/HNO3 solution (pH 1.0) for 2.5 h. The water oxidation mechanism and intermediate prod...

Description
Summary:Unlike [Ru2(μ-O2CCH3)4], the structurally analogous water-soluble Ru2II,III diphosphonato complex K3[Ru2(hedp)2(H2O)2] (K3·1) is only involved in stoichiometric water oxidation with a maximum 67% O2 yield under CAN/HNO3 solution (pH 1.0) for 2.5 h. The water oxidation mechanism and intermediate products were ascertained by UV-vis, ESI-MS and DFT calculation.
