Zinc Oxychlorides

Various oxychlorides have been described, but Driot, by determinations of the solubility of zinc oxide in aqueous solutions of zinc chloride, could only identify ZnCl₂.4ZnO.6H₂O and ZnCl₂.ZnO.1½H₂O. The former was isolated as an amorphous powder, losing 5 molecules of water at 200° C., and the latter as microscopic crystals, losing 1 molecule of water at 230° C. and decomposing at a higher temperature.
