Diruthenium tetraacetate chloride is the coordination polymer with the formula {[Ru2(O2CCH3)4]Cl}n. A red brown solid, the compound is obtained by the reduction of ruthenium trichloride in acetic acid.[1] The compound has attracted much academic interest because it features a fractional metal-metal bond order of 2.5.[2]

The [Ru2(O2CCH3)4]+ core adopts the Chinese lantern structure, with four acetate ligands spanning the Ru2 center. The Ru-Ru distance is 228 pm.[3][4] The [Ru2(O2CCH3)4]+ cages are linked by bridging chloride ligands.
