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,[2] and its dihydrate can be obtained by reacting samarium(III) chloride, iodine pentoxide and potassium periodate in water at 180 °C.[1]

Properties

Samarium(III) iodate decomposes as follows:[2]

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).[3]
