DyPS4 is Zircon-like structured and crystallizes in the tetragonal I4_1/acd space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 8-coordinate geometry to four equivalent S(1) and four equivalent S(2) atoms. In the second Dy site, Dy(2) is bonded to four equivalent S(1) and four equivalent S(2) atoms to form distorted DyS8 hexagonal bipyramids that share edges with four equivalent P(1)S4 tetrahedra. P(1) is bonded to two equivalent S(1) and two equivalent S(2) atoms to form PS4 tetrahedra that share edges with two equivalent Dy(2)S8 hexagonal bipyramids. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 3-coordinate geometry to one Dy(1), one Dy(2), and one P(1) atom. In the second S site, S(2) is bonded in a distorted T-shaped geometry to one Dy(1), one Dy(2), and one P(1) atom.
