Chemical chemical compound

Cobalt phosphate is the inorganic chemical compound with the formula Co_iii(PO_iv)_ii. It is a commercial inorganic pigment known every bit cobalt violet.^[2] Thin films of this material are h2o oxidation catalysts.^[three]

Preparation and construction [edit]

The tetrahydrate Co₃(PO₄)₂•4H₂O precipitates equally a solid upon mixing aqueous solutions of cobalt(Ii) and phosphate salts. Upon heating, the tetrahydrate converts to the anhydrous cloth. Co-ordinate to X-ray crystallography, the anhydrous Co₃(PO₄)₂ consists of discrete phosphate (PO ³⁻
_four ) anions that link Co ²⁺
centres. The cobalt ions occupy both octahedral (6-coordinate) and pentacoordinate sites in a 1:ii ratio.^[four] ^[5]
