DyS2 crystallizes in the tetragonal P4/nmm space group. Dy(1) is bonded in a 9-coordinate geometry to four equivalent S(2) and five equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded to five equivalent Dy(1) atoms to form a mixture of distorted corner and edge-sharing SDy5 trigonal bipyramids. In the second S site, S(2) is bonded in a 4-coordinate geometry to four equivalent Dy(1) atoms.
DyS2 crystallizes in the tetragonal P4/nmm space group. Dy(1) is bonded in a 9-coordinate geometry to four equivalent S(2) and five equivalent S(1) atoms. All Dy(1)-S(2) bond lengths are 2.90 Å. There are four shorter (2.83 Å) and one longer (2.84 Å) Dy(1)-S(1) bond length. There are two inequivalent S sites. In the first S site, S(1) is bonded to five equivalent Dy(1) atoms to form a mixture of distorted corner and edge-sharing SDy5 trigonal bipyramids. In the second S site, S(2) is bonded in a 4-coordinate geometry to four equivalent Dy(1) atoms.
