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]

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]
