Neodymium(III) iodate is an inorganic compound with the chemical formula Nd(IO₃)₃.

Preparation

Neodymium(III) iodate can be produced by the hydrothermal reaction of neodymium(III) nitrate or neodymium(III) oxide and iodic acid in water at 230 °C:^[1]

Nd(NO₃)₃ + 3 HIO₃ → Nd(IO₃)₃ + 3 HNO₃

Nd₂O₃ + 6 HIO₃ → 2 Nd(IO₃)₃ + 3 H₂O

Properties

Neodymium(III) iodate can be thermally decomposed as follows:^[2]

7 Nd(IO₃)₃ → Nd₅(IO₆)₃ + Nd₂O₃ + 9 I₂ + 21 O₂

Its monohydrate is known, crystallizing in the monoclinic crystal system, with space group P2₁, and its pyroelectric coefficient at room temperature is 2.2×10⁻⁵ C·m⁻²/K.^[3]
