Strontium selenide is an inorganic compound with the chemical formula SrSe.
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]
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]
