The crystal structure described by EuPSe3 crystallizes in the monoclinic P2_1/c space group. Eu(1) is bonded in a 8-coordinate geometry to two equivalent Se(1), three equivalent Se(2), and three equivalent Se(3) atoms. P(1) is bonded in a distorted tetrahedral geometry to one P(1), one Se(1), one Se(2), and one Se(3) atom. There are three inequivalent Se sites. In the first Se site, Se(1) is bonded in a distorted T-shaped geometry to two equivalent Eu(1) and one P(1) atom. In the second Se site, Se(2) is bonded in a 4-coordinate geometry to three equivalent Eu(1) and one P(1) atom. In the third Se site, Se(3) is bonded in a 4-coordinate geometry to three equivalent Eu(1) and one P(1) atom. is represented by the CIF file [CIF]
