The material structure described by Eu5(PO4)3F crystallizes in the hexagonal P6_3/m space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(3) atoms. In the second Eu site, Eu(2) is bonded in a 7-coordinate geometry to one O(1), one O(2), four equivalent O(3), and one F(1) atom. P(1) is bonded in a tetrahedral geometry to one O(1), one O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Eu(2), two equivalent Eu(1), and one P(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Eu(2), two equivalent Eu(1), and one P(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Eu(1), two equivalent Eu(2), and one P(1) atom. F(1) is bonded in a trigonal planar geometry to three equivalent Eu(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
