Caesium ytterbium diselenide, CsYbSe2, crystallizes in space group P63/mmc of the hexagonal system. It is isostructural with CsPrS2, which has the β-RbScO2 structure type. In the asymmetric unit, the site symmetries of atoms Cs, Yb and Se are 6̄m2, 3̄m and 3m, respectively. The structure comprises layers of edge-shared YbSe6 octahedra perpendicular to , with Cs atoms between the layers in a trigonal-prismatic arrangement.
