The salt is produced by hydrolysis of zirconium tetrachloride or treating zirconium oxide with hydrochloric acid.[2] It adopts a tetrameric structure, consisting of the cation [Zr4(OH)8]8+. features four pairs of hydroxide bridging ligands linking four Zr4+ centers. The chloride anions are not ligands, consistent with the high oxophilicity of Zr(IV).[1] The salt crystallizes as tetragonal crystals.[3]
