The compound described by ErPO4 is Zircon structured and crystallizes in the tetragonal I4_1/amd space group. Er(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. P(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. O(1) is bonded in a 3-coordinate geometry to two equivalent Er(1) and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
