Europium(III) iodate is an inorganic compound with the chemical formula Eu(IO3)3. It can be produced by hydrothermal reaction of europium(III) nitrate or europium(III) oxide and iodic acid in water at 230 °C. It can be thermally decomposed as follows:
- 7 Eu(IO3)3 → Eu5(IO6)3 Eu2O3 9 I2 21 O2
It reacts hydrothermally with iodine pentoxide and molybdenum trioxide at 200 °C to obtain Eu(MoO2)(IO3)4(OH).
