LiEuPSe4 crystallizes in the orthorhombic Ama2 space group. Li(1) is bonded in a 4-coordinate geometry to two equivalent Se(1) and two equivalent Se(3) atoms. Eu(1) is bonded in a 8-coordinate geometry to two equivalent Se(2), two equivalent Se(3), and four equivalent Se(1) atoms. P(1) is bonded in a tetrahedral geometry to one Se(2), one Se(3), and two equivalent Se(1) atoms. There are three inequivalent Se sites. In the first Se site, Se(1) is bonded in a 4-coordinate geometry to one Li(1), two equivalent Eu(1), and one P(1) atom. In the second Se site, Se(2) is bonded in a distorted T-shaped geometry to two equivalent Eu(1) and one P(1) atom. In the third Se site, Se(3) is bonded in a 5-coordinate geometry to two equivalent Li(1), two equivalent Eu(1), and one P(1) atom.
