Chromium acetate hydroxide


Chromium acetate hydroxide is the coordination complex with the formula 4. A dark violet solid, it crystallizes as the triacontatetrahydrate. It is water soluble.

Structure

The complex is a tetramer of binuclear Cr233. 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.
