Eu(DyS2)2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to one S(3), two equivalent S(1), and three equivalent S(4) atoms to form a mixture of edge and corner-sharing DyS6 octahedra. The corner-sharing octahedral tilt angles range from 48-66°. In the second Dy site, Dy(2) is bonded to one S(1), two equivalent S(3), and three equivalent S(2) atoms to form a mixture of edge and corner-sharing DyS6 octahedra. The corner-sharing octahedral tilt angles range from 48-66°. Eu(1) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent S(2), two equivalent S(3), and two equivalent S(4) atoms. There are four inequivalent S sites. In the first S site, S(1) is bonded to one Dy(2), two equivalent Dy(1), and two equivalent Eu(1) atoms to form a mixture of distorted edge and corner-sharing SEu2Dy3 trigonal bipyramids. In the second S site, S(2) is bonded to three equivalent Dy(2) and two equivalent Eu(1) atoms to form a mixture of edge and corner-sharing SEu2Dy3 square pyramids. In the third S site, S(3) is bonded to one Dy(1), two equivalent Dy(2), and two equivalent Eu(1) atoms to form a mixture of distorted edge and corner-sharing SEu2Dy3 trigonal bipyramids. In the fourth S site, S(4) is bonded to three equivalent Dy(1) and two equivalent Eu(1) atoms to form a mixture of distorted edge and corner-sharing SEu2Dy3 trigonal bipyramids.
