The crystal structure described by Ce2Te3 crystallizes in the tetragonal I-42d space group. There are three inequivalent Ce sites. In the first Ce site, Ce(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, corner, and face-sharing CeTe8 hexagonal bipyramids. In the second Ce site, Ce(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, corner, and face-sharing CeTe8 hexagonal bipyramids. In the third Ce site, Ce(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, corner, and face-sharing CeTe8 hexagonal bipyramids. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded to one Ce(3), two equivalent Ce(2), and three equivalent Ce(1) atoms to form distorted TeCe6 octahedra that share corners with three equivalent Te(1)Ce6 octahedra, corners with five equivalent Te(2)Ce5 square pyramids, corners with seven equivalent Te(3)Ce5 square pyramids, edges with two equivalent Te(1)Ce6 octahedra,  an edgeedge with one Te(3)Ce5 square pyramid, edges with three equivalent Te(2)Ce5 square pyramids, faces with two equivalent Te(1)Ce6 octahedra,  a faceface with one Te(2)Ce5 square pyramid, and faces with two equivalent Te(3)Ce5 square pyramids. The corner-sharing octahedral tilt angles range from 16-51°. In the second Te site, Te(2) is bonded to one Ce(2), two equivalent Ce(1), and two equivalent Ce(3) atoms to form distorted TeCe5 square pyramids that share corners with five equivalent Te(1)Ce6 octahedra, corners with four equivalent Te(2)Ce5 square pyramids, corners with four equivalent Te(3)Ce5 square pyramids, edges with three equivalent Te(1)Ce6 octahedra,  an edgeedge with one Te(2)Ce5 square pyramid, edges with four equivalent Te(3)Ce5 square pyramids,  a faceface with one Te(1)Ce6 octahedra, and  a faceface with one Te(2)Ce5 square pyramid. The corner-sharing octahedral tilt angles range from 19-48°. In the third Te site, Te(3) is bonded to one Ce(2), one Ce(3), and three equivalent Ce(1) atoms to form distorted TeCe5 square pyramids that share corners with seven equivalent Te(1)Ce6 octahedra, corners with four equivalent Te(2)Ce5 square pyramids, corners with five equivalent Te(3)Ce5 square pyramids,  an edgeedge with one Te(1)Ce6 octahedra, edges with four equivalent Te(2)Ce5 square pyramids, faces with two equivalent Te(1)Ce6 octahedra, and  a faceface with one Te(3)Ce5 square pyramid.
