'''硒化銣'''是一種無機化合物，由[[硒]]和[[銣]]，為一種[[氫硒酸]]鹽，其化學式為Rb<sub>2</sub>Se。

== 制備 ==
'''硒化銣'''可以用[[汞硒化物]]和[[銣]][[單質]]反應而制得。<ref name="Bergmann">Alfred Bergmann: ''Über die Darstellung und Eigenschaften von Caesium-und Rubidium-Sulfid, Selenid und Tellurid.'' In: ''Zeitschr. f. anorg. u. allg. Chem.'' 1937, 231, 3, S. 269–280, {{doi|10.1002/zaac.19372310306}}.</ref>

可將[[硒化氫]]（[[氫硒酸]]）溶解在[[氫氧化銣]]水溶液，最終會形成硒化銣。<ref name='Abegg'>R. Abegg, F. Auerbach: 'Handbuch der anorganischen Chemie'. Verlag S. Hirzel, Bd. 2, 1908. S. 430.[http://www.archive.org/stream/handbuchderanor09koppgoog#page/n449/mode/2up Volltext]</ref>此法與制備[[硫化銣]]的方法類似，因為它們都是[[氧族]][[化合物|化物]]。

: RbOH + H<sub>2</sub>Se → RbHSe + H<sub>2</sub>O
: RbHSe + RbOH → Rb<sub>2</sub>Se + H<sub>2</sub>O

== 晶體結構 ==
