Abstract
The crystal structure of a single crystal of dysprosium polysulfide DyS1.83 = Dy6S11 is determined. The unit cell parameters are similar to those established for DyS1.76 = Dy4S7, but the composition is different. The unit cell is monoclinic, space group P21/m, a = 11.009(2), b = 11.531(2), c = 11.023(1) Å, β = 91.152(8)∘, V= 1398.1(4) Å3; for Z = 4 this gives the composition Dy6S11, regarding the experimental values of the partial statistic of the S atoms and dcalc = 6.303 g/cm3 (EnrafNonius CAD-4 automatic diffractometer, γMoKα, Raniso = 0.0349 for 6381 unique Ihkl > 2σI of 9804 measured ones). An empirical absorption correction was applied based on transmission curves and habit data. The polysulfide is a PbFCl type structure; the monoclinic unit cell parameters are related to a0 and c0 of the tetragonal cell of PbFCl as [101] ≅ 4a0, [010] ≅3a0, [101] ≅2c0. The crystal is a twin with the ratio of components k2 = 1-k1 = 0.243(2) and a transition matrix 001/010/100. The composition DyS1.83±0.02 agrees with the chemical analysis data and the experimental value dexp = 6.30±0.08 g/cm3. The phase individuality of the polysulfide is confirmed by the form of the P-T projection of the P-T-X diagram of the Dy-S system.
