The structure described by Ce2SiTeO4 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 6-coordinate geometry to three equivalent Te(1), two equivalent O(2), and four equivalent O(1) atoms. In the second Ce site, Ce(2) is bonded in a 6-coordinate geometry to four equivalent Te(1), two equivalent O(1), and four equivalent O(2) atoms. Si(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. Te(1) is bonded in a 7-coordinate geometry to three equivalent Ce(1) and four equivalent Ce(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Ce(2), two equivalent Ce(1), and one Si(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Ce(1), two equivalent Ce(2), and one Si(1) atom. is represented by the CIF card [CIF]
