U2Te3 crystallizes in the tetragonal I-42d space group. There are three inequivalent U sites. In the first U site, U(1) is bonded to two equivalent Te(2), three equivalent Te(1), and three equivalent Te(3) atoms to form a mixture of distorted edge, face, and corner-sharing UTe8 hexagonal bipyramids. In the second U site, U(2) is bonded to two equivalent Te(2), two equivalent Te(3), and four equivalent Te(1) atoms to form a mixture of distorted edge, face, and corner-sharing UTe8 hexagonal bipyramids. In the third U site, U(3) is bonded to two equivalent Te(1), two equivalent Te(3), and four equivalent Te(2) atoms to form a mixture of distorted edge, face, and corner-sharing UTe8 hexagonal bipyramids. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded to one U(3), two equivalent U(2), and three equivalent U(1) atoms to form distorted TeU6 octahedra that share corners with three equivalent Te(1)U6 octahedra, corners with five equivalent Te(2)U5 square pyramids, corners with seven equivalent Te(3)U5 square pyramids, edges with two equivalent Te(1)U6 octahedra,  an edgeedge with one Te(3)U5 square pyramid, edges with three equivalent Te(2)U5 square pyramids, faces with two equivalent Te(1)U6 octahedra,  a faceface with one Te(2)U5 square pyramid, and faces with two equivalent Te(3)U5 square pyramids.
