BaU2Te5 crystallizes in the tetragonal I4/mcm space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent Te(2) and eight equivalent Te(1) atoms. U(1) is bonded in a 8-coordinate geometry to two equivalent Te(2) and six equivalent Te(1) atoms. There are two inequivalent Te sites. In the first Te site, Te(2) is bonded to two equivalent Ba(1) and four equivalent U(1) atoms to form TeBa2U4 octahedra that share corners with six equivalent Te(2)Ba2U4 octahedra, corners with sixteen equivalent Te(1)Ba2U3 square pyramids, and faces with eight equivalent Te(1)Ba2U3 square pyramids. The corner-sharing octahedral tilt angles range from 0-42°. In the second Te site, Te(1) is bonded to two equivalent Ba(1) and three equivalent U(1) atoms to form distorted TeBa2U3 square pyramids that share corners with four equivalent Te(2)Ba2U4 octahedra, corners with twelve equivalent Te(1)Ba2U3 square pyramids, edges with seven equivalent Te(1)Ba2U3 square pyramids, faces with two equivalent Te(2)Ba2U4 octahedra, and  a faceface with one Te(1)Ba2U3 square pyramid. The corner-sharing octahedral tilt angles range from 45-61°.
BaU2Te5 crystallizes in the tetragonal I4/mcm space group. Ba(1) is bonded in a 10-coordinate geometry to two equivalent Te(2) and eight equivalent Te(1) atoms. Both Ba(1)-Te(2) bond lengths are 3.79 Å. All Ba(1)-Te(1) bond lengths are 3.66 Å. U(1) is bonded in a 8-coordinate geometry to two equivalent Te(2) and six equivalent Te(1) atoms. Both U(1)-Te(2) bond lengths are 3.18 Å. There are two shorter (3.10 Å) and four longer (3.26 Å) U(1)-Te(1) bond lengths. There are two inequivalent Te sites. In the first Te site, Te(2) is bonded to two equivalent Ba(1) and four equivalent U(1) atoms to form TeBa2U4 octahedra that share corners with six equivalent Te(2)Ba2U4 octahedra, corners with sixteen equivalent Te(1)Ba2U3 square pyramids, and faces with eight equivalent Te(1)Ba2U3 square pyramids.
