Neodymium(III) iodate

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:


 * 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:


 * 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.
