Manganese titelluride is an inorganic chemical compound of manganese from the group of tellurides .

Extraction and presentation

Manganese titelluride can be obtained by reacting stoichiometric amounts of manganese and tellurium in the absence of air.

${\displaystyle \mathrm {Mn+2\ Te\longrightarrow MnTe_{2}} }$

properties

Manganese titelluride is an odorless solid that is practically insoluble in water. At temperatures below 83.8 K it is antiferromagnetic . Above its melting temperature, the compound decomposes to form manganese telluride and tellurium. Manganese titelluride has a cubic crystal structure of the pyrite type with the space group Pa 3 (space group no. 205) . Above 7 GPa, this changes into an orthorhombic crystal structure of the marcasite type .

use

Manganese titelluride is used as an intermediate in the production of other chemical compounds.
