Europium(II) telluride is an inorganic compound of europium and tellurium, with the chemical formula EuTe.

Preparation

Europium(II) telluride can be prepared by the reaction of europium and tellurium at 500–1000 °C.

Eu + Te → EuTe

The compound can also be prepared by reacting europium(II) hydride and tellurium in a stream of hydrogen at 600–850 °C:

EuH₂ + Te → EuTe + H₂

Properties

Europium(II) telluride is a black antiferromagnetic solid with a cubic crystal structure of the NaCl-type.
