The crystal structure described by Eu5P3O12Cl 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 8-coordinate geometry to one O(2), one O(3), four equivalent O(1), and two equivalent Cl(1) atoms. P(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to one Eu(1), two equivalent Eu(2), 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(2), two equivalent Eu(1), and one P(1) atom. Cl(1) is bonded to six equivalent Eu(2) atoms to form face-sharing ClEu6 octahedra. is represented by the CIF file [CIF]
