Lutetium(III) iodide or lutetium iodide is an inorganic compound consisting of iodine and lutetium, with the chemical formula of LuI3.

Contents

Preparation

Lutetium(III) iodide can be obtained by reacting lutetium with iodine: [5] [2]

2 Lu + 3 I2 → LuI3

Lutetium(III) iodide can also obtained by the reacting metallic lutetium with mercury iodide in vacuum at 500 °C: [5]

2 Lu + 3 HgI2 → 2 LuI3 + 3 Hg

The elemental mercury generated in the reaction can be removed by distillation. [6]

The lutetium(III) iodide hydrate crystallized from the solution can be heated with ammonium iodide to obtain the anhydrate. [7] [5]

Properties

It is a brown, very hygroscopic solid with a bismuth(III) iodide-type crystal structure. In air, it quickly absorbs moisture and forms hydrates. [2] [3] [4] The corresponding oxide iodide is also readily formed at elevated temperature. [5]

Lutetium(III) iodide doped with cerium is designed for use in PET scanners. [8] Lutetium iodide can be used together with yttrium iodide and gadolinium iodide in LuI3-YI3-GdI3 scintillators to detect neutron and gamma radiation. [9]

<span class="mw-page-title-main">Nitrogen triiodide</span> Chemical compound

Nitrogen triiodide is an inorganic compound with the formula NI3. It is an extremely sensitive contact explosive: small quantities explode with a loud, sharp snap when touched even lightly, releasing a purple cloud of iodine vapor; it can even be detonated by alpha radiation. NI3 has a complex structural chemistry that is difficult to study because of the instability of the derivatives. Although nitrogen is more electronegative than iodine, the compound was so named due to its analogy to the compound nitrogen trichloride.

An iodide ion is the ion I−. Compounds with iodine in formal oxidation state −1 are called iodides. In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate. Worldwide, iodine deficiency affects two billion people and is the leading preventable cause of intellectual disability.
