The structure described by CsEuPO4 crystallizes in the orthorhombic Pnma space group. Cs(1) is bonded in a 10-coordinate geometry to one O(2), three equivalent O(3), and six equivalent O(1) atoms. Eu(1) is bonded in a 9-coordinate geometry to two equivalent O(3), three equivalent O(2), and four equivalent O(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 distorted single-bond geometry to three equivalent Cs(1), two equivalent Eu(1), and one P(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Cs(1), three equivalent Eu(1), and one P(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to three equivalent Cs(1), two equivalent Eu(1), and one P(1) atom. is represented by the CIF file [CIF]
