Chromium acetate hydroxide is the coordination complex with the formula [Cr2(OH)3(OAc)3]4. A dark violet solid, it crystallizes as the triacontatetrahydrate (34 molecules of water of crystallization). It is water soluble.{{cite journal |doi=10.1021/ic9907009|title=Polynuclear Chromium(III) Carboxylates. 1.

Structure
The complex is a tetramer of binuclear Cr2(OH)3(OAc)3. The subunits are linked by acetate and hydroxide ligands. The oxidation state of chromium is +3, which explains the stability of the complex since octahedral d3 ions give kinetically robust complexes. Overall, the complex's structure is unusual compared to other transition metal carboxylate complexes.
