properties

Sodium telluride is a moisture-sensitive, white, odorless solid that immediately decomposes in air, giving it a dark color. It is soluble in water, whereby the solution quickly deposits black, powdery tellurium when exposed to air. It crystallizes in the cubic anti-calcium fluoride type with the space group Fm 3 m (space group no. 225) . Template: room group / 225

use

Sodium telluride can be used in organic syntheses.
