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.
