Abstract (in english)
   The crystal structure of pyrargyrite, Ag3SbS3, from Příbram-Háje (Czech Republic) was refined from single-crystal X-ray diffraction data in the space group R3c to an R factor of 0.0112. In order to mimic the spread of electron density of silver, the non-harmonic Gram-Charlier development of the silver atomic displacement parameters was applied. The analysis of potential barriers between Ag sites reveals that silver transfer is equally probable not only within the Ag-S-Ag spirals and the Ag-Ag chains, but also between these spirals and chains.
