The material described by Ce2Te3 is Stibnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to two equivalent Te(1), two equivalent Te(3), and three equivalent Te(2) atoms to form a mixture of distorted corner and edge-sharing CeTe7 pentagonal bipyramids. In the second Ce site, Ce(2) is bonded in a 8-coordinate geometry to two equivalent Te(2), three equivalent Te(1), and three equivalent Te(3) atoms. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent Ce(1) and three equivalent Ce(2) atoms to form a mixture of distorted corner and edge-sharing TeCe5 trigonal bipyramids. In the second Te site, Te(2) is bonded to two equivalent Ce(2) and three equivalent Ce(1) atoms to form a mixture of corner and edge-sharing TeCe5 square pyramids. In the third Te site, Te(3) is bonded in a 5-coordinate geometry to two equivalent Ce(1) and three equivalent Ce(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
