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

The core adopts the Chinese lantern structure, with four acetate ligands spanning the Ru₂ center. The Ru-Ru distance is 228 pm. The units are linked by bridging chloride ligands.
