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.
