The structure described by Gd2SiTeO4 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 6-coordinate geometry to two equivalent Te(1), two equivalent O(2), and four equivalent O(1) atoms. In the second Gd site, Gd(2) is bonded in a 6-coordinate geometry to three 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 5-coordinate geometry to two equivalent Gd(1) and three equivalent Gd(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Gd(2), two equivalent Gd(1), and one Si(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Gd(1), two equivalent Gd(2), and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
