Lanthanum diiodide is an iodide of lanthanum, with the chemical formula of LaI2. It is an electride, actually having a chemical formula of La3+[(I−)2e−].
Preparation
Lanthanum diiodide can be obtained from the reduction of lanthanum(III) iodide with lanthanum metal under a vacuum at 800 to 900 °C:
La + 2 LaI3 → LaI2
It can also be obtained by reacting lanthanum and mercury(II) iodide:
La + HgI2 → LaI2 + Hg
It was first created by John D. Corbett in 1961.
Properties
Lanthanum diiodide is a blue-black solid with metallic lustre, which is easily hydrolyzed into the iodide oxide. It has a MoSi2-type structure, with the space group I4/mmm (No. 139).
