Abstract (in english)
   GeSnS3 and GeO2 have recently been found in a burning dump pile at the Kateřina colliery in Radvanice near Trutnov, Eastern Bohemia. The germanium compounds were recently formed through sublimation, together with a variety of additional phases, containing As, Sr, Pb, Sb, Bi, Cd and Mo from escaping gasses and vapors. GeSnS3 is monoclinic, and has unit cell dimensions of: a=7.256(3), b=10.227(6), c=6.854(3) (A), ß=105.469(5), V=490.2(4)A3, with a space group of P21/c and Z=4. The strongest powder diffraction maxima are: 6.97/100, 2.800/18, 2.695/26, 1.722/14. GeO2 is hexagonal, with unit cell dimensions of: a=4.982(6), c=6.65(1) (A), =121.4(4) A3, with a space group of P3221 and Z=3. The powder diffraction pattern includes: 4.31/31, 3.426/100, 2.488/22, 2.362/27, 2.280/24, 2.156/25
