Promethium iodate is an inorganic compound with the chemical formula Pm(IO₃)₃. It can be obtained by reacting with potassium iodate, ammonium iodate or a slight excess of iodic acid and Pm solution and precipitating it. Its hydrate, Pm(IO₃)₃·H₂O, crystallizes in the P2₁ space group, with unit cell parameters a=10.172±13, b=6.700±20, c=7.289±24 Å, β=113.1±0.2°.
