Abstract

Black single crystals of Cs₂U₂(P₂Se₉)(Se₂)₂ were synthesized at 1023 K by a solid-state reaction. Its structure was determined by single-crystal X-ray diffraction methods. The compound is isostructural with Rb₂U₂(P₂Se₉)(Se₂)₂ and Cs₂Th₂(P₂Se₉)(Se₂)₂ compounds, and crystallizes in the orthorhombic space group Pbca. Cs₂U₂(P₂Se₉)(Se₂)₂ displays a three-dimensional structure comprising USe₉ polyhedra connected via the Se₂ ^2– and P₂Se₉ species with channels filled by Cs atoms. From electronic structure calculations the compound is found to be a metal with a ferromagnetic arrangement of the magnetic moments.
