Single crystals of CsU2Te6 were synthesized from the reaction of U, Te, and Cs2Te3 at 1273 K. CsU2Te6 crystallizes in the space group Cmcm in the CsTh2Te6 structure type. The asymmetric unit comprises one U (site symmetry m2m), one Cs (m2m; half-occupancy) and two Te atoms (m.. and m2m). The structure of CsU2Te6 consists of infinite [U2Te6] layers perpendicular to [010] separated by Cs atoms. There are infinite Te—Te—Te linear chains along [001].
