Ce3Te4 crystallizes in the cubic I-43d space group. The structure is three-dimensional. Ce is bonded to eight equivalent Te atoms to form a mixture of distorted corner, edge, and face-sharing CeTe8 hexagonal bipyramids. There are four shorter (3.23 Å) and four longer (3.37 Å) Ce–Te bond lengths. Te is bonded to six equivalent Ce atoms to form a mixture of distorted corner, edge, and face-sharing TeCe6 octahedra. The corner-sharing octahedra tilt angles range from 16–50°.
