The crystal structure of the synthetic analogue of the mineral temagamite, Pd3HgTe3, was solved and refined to an R-factor of 0.0522 from single-crystal X-ray diffraction data. The structure is trigonal, space group P3m1. Layer modules (A–F) stacked along the c-axis form the crystal structure of Pd3HgTe3. Module A is composed of isolated octahedra [PdTe6], which share faces with adjacent octahedra from neighbouring modules. The edge-sharing [PdTe6] octahedra and [PdTe4] squares form the modules B and F, whereas the corner-sharing [PdTe4] squares constitute modules C, D and E. The Hg atoms occupy the anti-cubooctahedral voids formed by Te atoms.
