The crystal structure of sopcheite, Ag4Pd3Te4, has been solved using single-crystal diffraction data for a crystal from the Lukkulaisvaara intrusion, Karelia. Sopcheite crystallizes in a layered structure. The crystal structure is stabilised by a number of metal–metal interactions. The crystal structure of the synthetic phase Ag4Pd3Te4 was also determined by single-crystal X-ray diffraction (XRD). It corresponds to the structure of sopcheite from the Lukkulaisvaara intrusion. Electron backscatter diffraction data obtained on material from other reported sopcheite occurrences are entirely consis tent with this structure model, which is however incompatible with the sole powder XRD pattern reported so far for sopcheite.
