Eu(HoS2)2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded to one S(3), two equivalent S(1), and three equivalent S(4) atoms to form a mixture of corner and edge-sharing HoS6 octahedra. The corner-sharing octahedral tilt angles range from 48-65°. In the second Ho site, Ho(2) is bonded to one S(1), two equivalent S(3), and three equivalent S(2) atoms to form a mixture of corner and edge-sharing HoS6 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 one Ho(2), two equivalent Ho(1), and two equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing SEu2Ho3 trigonal bipyramids. In the second S site, S(2) is bonded to three equivalent Ho(2) and two equivalent Eu(1) atoms to form a mixture of corner and edge-sharing SEu2Ho3 square pyramids. In the third S site, S(3) is bonded to one Ho(1), two equivalent Ho(2), and two equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing SEu2Ho3 trigonal bipyramids. In the fourth S site, S(4) is bonded to three equivalent Ho(1) and two equivalent Eu(1) atoms to form a mixture of distorted corner and edge-sharing SEu2Ho3 trigonal bipyramids.
