Ruthenium(III) acetate, commonly known as basic ruthenium acetate, ^[1] describes a family of salts where the cation has the formula [Ru₃O(O₂CCH₃)₆(OH₂)₃]⁺. A representative derivative is the dihydrate of the tetrafluoroborate salt [Ru₃O(O₂CCH₃)₆(OH₂)₃]BF₄(H₂O)₂, which is the source of the data in the table above. ^[2] This and related salts are forest green, air-stable solids that are soluble in alcohols.

Basic ruthenium acetate features octahedral Ru(III) centers, a triply bridging oxo ligand, six acetate ligands, and three aquo ligands. The same structure is shared with basic acetates of iron, chromium, Iridium(III) acetate|iridium]], and manganese. ^{[1] [2]}

Preparation and reactions

It is prepared by heating ruthenium trichloride in acetic acid in the presence of sodium acetate. ^[3] The basic acetates of ruthenium were reported in the early 1950s but were not properly formulated. ^[4]

Basic ruthenium acetate reacts with many ligands such as triphenylphosphine and pyridine concomitant with reduction. These derivatives [Ru₃O(O₂CCH₃)₆L₃]⁰ are mixed valence compounds. ^[5]
