Chemical compound
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."
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.
Chemical properties※
Rubidium sulfide reacts with sulfur in hydrogen gas to form rubidium pentasulfide, Rb2S5.
