It is a commercial inorganic pigment known as cobalt violet.[1] Thin films of this material are water oxidation catalysts.[2] Preparation and structureThe tetrahydrate CoPO4(H2O)4 precipitates as a solid upon mixing aqueous solutions of cobalt(II) and phosphate salts. Upon heating, the tetrahydrate converts to the anhydrous material. According to X-ray crystallography, the anhydrous CoPO4 consists of discrete phosphate ({{chem|PO|4|3-}}) anions that link {{chem|Co|2+}} centres. The cobalt ions occupy both octahedral (six-coordinate) and pentacoordinate sites in a 1:2 ratio.[3][4] {{clear|left}}See also
