U3Te4 crystallizes in the trigonal R3c space group. U(1) is bonded to two equivalent Te(2) and six equivalent Te(1) atoms to form a mixture of distorted face, corner, and edge-sharing UTe8 hexagonal bipyramids. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to six equivalent U(1) atoms to form a mixture of distorted face, corner, and edge-sharing TeU6 octahedra. The corner-sharing octahedral tilt angles range from 16-50°. In the second Te site, Te(2) is bonded to six equivalent U(1) atoms to form a mixture of distorted face, corner, and edge-sharing TeU6 octahedra. The corner-sharing octahedral tilt angles range from 17-50°.
U3Te4 crystallizes in the trigonal R3c space group. U(1) is bonded to two equivalent Te(2) and six equivalent Te(1) atoms to form a mixture of distorted face, corner, and edge-sharing UTe8 hexagonal bipyramids. There is one shorter (3.21 Å) and one longer (3.37 Å) U(1)-Te(2) bond length. There are a spread of U(1)-Te(1) bond distances ranging from 3.20-3.37 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to six equivalent U(1) atoms to form a mixture of distorted face, corner, and edge-sharing TeU6 octahedra.
