The structure described by 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°. is represented by the CIF file [CIF]
