The material structure described by U3Te5 crystallizes in the orthorhombic Pnma space group. There are two inequivalent U sites. In the first U site, U(1) is bonded in a 8-coordinate geometry to two equivalent Te(1), two equivalent Te(2), two equivalent Te(3), and two equivalent Te(4) atoms. In the second U site, U(2) is bonded to one Te(2), one Te(3), one Te(4), and four equivalent Te(1) atoms to form distorted edge-sharing UTe7 pentagonal bipyramids. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent U(1) and two equivalent U(2) atoms to form distorted TeU4 trigonal pyramids that share corners with two equivalent Te(4)U5 square pyramids, corners with four equivalent Te(3)U5 square pyramids, corners with two equivalent Te(2)U5 trigonal bipyramids, corners with six equivalent Te(1)U4 trigonal pyramids,  an edgeedge with one Te(3)U5 square pyramid, edges with two equivalent Te(4)U5 square pyramids, edges with two equivalent Te(2)U5 trigonal bipyramids, and  an edgeedge with one Te(1)U4 trigonal pyramid. In the second Te site, Te(2) is bonded to one U(2) and four equivalent U(1) atoms to form distorted TeU5 trigonal bipyramids that share  a cornercorner with one Te(4)U5 square pyramid, corners with five equivalent Te(3)U5 square pyramids, corners with four equivalent Te(2)U5 trigonal bipyramids, corners with four equivalent Te(1)U4 trigonal pyramids, edges with two equivalent Te(3)U5 square pyramids, edges with four equivalent Te(4)U5 square pyramids, and edges with four equivalent Te(1)U4 trigonal pyramids. In the third Te site, Te(3) is bonded to one U(2) and four equivalent U(1) atoms to form TeU5 square pyramids that share corners with four equivalent Te(4)U5 square pyramids, corners with five equivalent Te(2)U5 trigonal bipyramids, corners with eight equivalent Te(1)U4 trigonal pyramids,  an edgeedge with one Te(4)U5 square pyramid, edges with two equivalent Te(3)U5 square pyramids, edges with two equivalent Te(2)U5 trigonal bipyramids, edges with two equivalent Te(1)U4 trigonal pyramids, and  a faceface with one Te(4)U5 square pyramid. In the fourth Te site, Te(4) is bonded to one U(2) and four equivalent U(1) atoms to form TeU5 square pyramids that share corners with four equivalent Te(3)U5 square pyramids, corners with four equivalent Te(4)U5 square pyramids,  a cornercorner with one Te(2)U5 trigonal bipyramid, corners with four equivalent Te(1)U4 trigonal pyramids,  an edgeedge with one Te(3)U5 square pyramid, edges with four equivalent Te(2)U5 trigonal bipyramids, edges with four equivalent Te(1)U4 trigonal pyramids, and  a faceface with one Te(3)U5 square pyramid. is represented by the CIF card [CIF]
