Abstract (in english)
   Crystal structure of pseudojohannite from White Canyon, USA, is described based on 2664 observed diffractions from single-crystal diffractiometer. The triclinic unit cell with a cell dimensions of a = 8.6744(4), b = 8.8692(4), c = 10.0090(5)A, ? = 72.105(4)°, ? = 70.544(4)°, ? = 76.035(4)° and V = 682.61(5) A3 , with Z = 1, was chosen. Based on results of the refinement and bond-valence analysis, the structural formula of pseudojohannite is Cu2.94H0.06+(OH)2[(UO2)4O4(SO4)2](H2O)12, Z = 1.
