Abstract

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 [001], with Cs atoms between the layers in a trigonal-prismatic arrangement.
