The material structure described by Eu(ErS2)2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Er sites. In the first Er site, Er(1) is bonded to one S(4), two equivalent S(2), and three equivalent S(1) atoms to form a mixture of corner and edge-sharing ErS6 octahedra. The corner-sharing octahedral tilt angles range from 48-65°. In the second Er site, Er(2) is bonded to one S(2), two equivalent S(4), and three equivalent S(3) atoms to form a mixture of corner and edge-sharing ErS6 octahedra. The corner-sharing octahedral tilt angles range from 48-65°. 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 three equivalent Er(1) and two equivalent Eu(1) atoms to form a mixture of corner and edge-sharing SEu2Er3 square pyramids. In the second S site, S(2) is bonded to one Er(2), two equivalent Er(1), and two equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing SEu2Er3 trigonal bipyramids. In the third S site, S(3) is bonded to three equivalent Er(2) and two equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing SEu2Er3 trigonal bipyramids. In the fourth S site, S(4) is bonded to one Er(1), two equivalent Er(2), and two equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing SEu2Er3 trigonal bipyramids. is represented by the CIF card [CIF]
