| Abstract/Notes | The crystal structure of dadsonite, ideally Pb23Sb25S60Cl, a 8.276(2), b 17.392(4), c 19.505(4) Å, α 83.527(7), β 77.882(8), γ 89.125(8)°, V 2727.2(9), space group P1̅ and Z = 1, from the Klačianka hydrothermal deposit, in the Low Tatra Mountains of Slovakia, has been refined to an R1 index of 4.90% for 5263 unique reflections [Fo 2 ≥ 2σ(F2)] measured with MoKα radiation on a three-circle diffractometer equipped with a CCD detector. There are 10 pure Pb and 8 Sb sites, as well as three mixed (Pb,Sb) and (Sb,Pb) sites and three split coordinations of Sb in the crystal structure. Thirty S positions and one presumed Cl position, designated as “S1”, constitute the anion part of the structure. The structure is of a rod-layer type, with two types of rod-layers alternating along the stacking direction b. Dadsonite is a desymmetrized OD structure with profuse twinning. The two types of layers present possess layer symmetries p1̅ and b2/m11, respectively. These layers respectively have a pseudoperiodicity equal to a/2 and a set of elements of pseudosymmetry which together cause a disorder process. |
