Rubidium sulfide is an inorganic compound and a salt with the chemical formula Rb2S. It is a white solid with similar properties to other alkali metal sulfides.
Production
By dissolving hydrogen sulfide into rubidium hydroxide solution, it will produce rubidium bisulfide, followed by rubidium sulfide.[3][4]
Properties
Physical properties
Rubidium sulfide has a cubic crystal similar to lithium sulfide, sodium sulfide and potassium sulfide, known as the anti-fluorite structure. Their space groups are . Rubidium sulfide has a crystal lattice unit cell dimension of = 765.0 pm.[1]
Chemical properties
Rubidium sulfide reacts with sulfur in hydrogen gas to form rubidium pentasulfide, Rb2S5.[4][5]
