The compound described by TbGd(PO4)2 is Zircon-derived structured and crystallizes in the tetragonal I-4m2 space group. Tb(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Gd(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. In the second P site, P(2) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Tb(1), one Gd(1), and one P(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Tb(1), one Gd(1), and one P(2) atom. is represented by the CIF file [CIF]
