Zirconyl chloride is the inorganic compound with the formula of [Zr<sub>4</sub>(OH)<sub>8</sub>(H<sub>2</sub>O)<sub>16</sub>]Cl8(H2O)12, more commonly written ZrOCl2·8H2O, and referred to as zirconyl chloride octahydrate. It is a white solid and is the most common water-soluble derivative of zirconium. A compound with the formula ZrOCl2 has not been characterized.
and zirconyl chloride.]]The salt is produced by hydrolysis of zirconium tetrachloride or treating zirconium oxide with hydrochloric acid.[1] It adopts a tetrameric structure, consisting of the cation [Zr<sub>4</sub>(OH)<sub>8</sub>]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). The salt crystallizes as tetragonal crystals.[2]
