RuH2O63
RuH2O63 is a shorthand notation for the hexaaquaruthenium(III) cation, [Ru(H2O)6]3+. In aqueous solution this species represents ruthenium in the +3 oxidation state coordinated by six water molecules. The conventional way to denote it in chemical formulas is [Ru(H2O)6]3+; the simplified form underscores its aquated nature.
Structure and properties: The six water ligands arrange around ruthenium in an octahedral geometry. The complex
Formation and reactions: Hexaaquaruthenium(III) forms when Ru(III) salts such as RuCl3 are dissolved in water and,
Applications and context: As a common ruthenium(III) aqua starting material, [Ru(H2O)6]3+ is used in inorganic synthesis,
