Zirconyl chloride is the

inorganic compound In chemistry, an inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as '' inorganic chemist ...

with the formula of r₄(OH)₈(H₂O)₁₆l₈(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.
