Rubidium selenide is an inorganic compound composed of

photovoltaic cells.[5]

Preparation

Rubidium selenide can be prepared by reacting mercury selenide and metallic rubidium.[6] The elements can be synthesized in liquid ammonia.[7]

Hydrogen selenide can also be dissolved in an aqueous solution of rubidium hydroxide to eventually form rubidium selenide.[8] This method is similar to the method for preparing rubidium sulfide, because they are both chalcogenide compounds.

RbOH + H2Se → RbHSe + H2O
RbHSe + RbOH → Rb2Se + H2O

Crystal structure

Rubidium selenide has

antifluorite
structure, and the space group is and the lattice parameters are a=801.0 pm, per unit. The unit cell has 4 units.[1]
