Strontium selenide is an inorganic compound with the chemical formula SrSe.
Preparation
[edit]Strontium selenide can be prepared by reducing strontium selenate with hydrogen at 600 °C.[2] It can also be produced by reacting strontium and hydrogen selenide in liquid ammonia.[3]
Properties
[edit]Strontium selenide crystallizes in the orthorhombic crystal system with space group Fm3m. It has a NaCl structure.[4][5] It transforms into a CsCl structure with a space group Pm3m under high pressure (14 GPa).[6]
It reacts with mercury selenide and germanium diselenide at high temperature to obtain the SrHgGeSe4 crystal.[7] It reacts with thorium and selenium at high temperature in the presence of tin to obtain SrTh2Se5.[8]
