The synthetic analogue of the mineral tischendorfite, Pd8Hg3Te9, was prepared and its crystal structure was solved and refined from powder X-ray diffraction data. The crystal structure is orthorombic, space group Pmmn. Tischendorfite crystallizes in a framework structure, where Pd atoms show two types of coordination by Se atoms. The Hg atoms occupy the anti-cubooctahedral voids. The structure is stabilized by a system of Pd-Hg and Pd-Pd metallic bonds
