Samarium(III) iodate

Samarium iodate is an inorganic compound with the chemical formula Sm(IO3)3.

Properties
Samarium(III) iodate monohydrate can be obtained by reacting samarium(III) nitrate and potassium iodate in boiling water, and its dihydrate can be obtained by reacting samarium(III) chloride, iodine pentoxide and potassium periodate in water at 180 °C.

Properties
Samarium(III) iodate decomposes as follows:


 * 7 Sm(IO3)3 → Sm5(IO6)3 + Sm2O3 + 9 I2 + 21 O2

It undergoes a hydrothermal reaction with iodine pentoxide and molybdenum trioxide at 200 °C to obtain Sm(MoO2)(IO3)4(OH).
