The crystal structure of watkinsonite, Cu2PbBi4Se8, from the Zálesí uranium deposit, Czech Republic
Original language description
The crystal structure of sulfur-free watkinsonite, ideally Cu2PbBi4Se8, monoclinic, a 12.952(4), b 4.152(1), c 15.155(5) angstrom, beta 108.93(1) degrees, space group P2(1)/m, Z = 2, part of the selenide mineralization of the uranium deposit of Zalesi, Czech Republic, has been solved by direct methods and refined to R-1 = 4.61% on the basis of 1287 unique reflections [F-o > 4 sigma(F-o)] collected on a Bruker P3 diffractometer with a CCD detector and MoK alpha radiation. The crystal structure contains one Pb site, four Bi sites, two Cu sites and eight Se sites. Partial replacement of one Cu (in a linearly coordinated site) by Ag is observed. The crystal structure consists of (100)(PbS) slabs four atomic planes thick of a galena-like structure alternating with single layers of hexagonally packed selenium.
