The crystal structure of natural orthorhombic Ag0.71Pb1.52Bi1.32Sb1.45S6, a lillianite homologue with N = 4, from hydrothermal veins at Kutna Hora in central Bohemia, Czech Republic, has been refined from single-crystal X-ray data. The structure contains seven independent positions: three metal sites M1, M2 and M3 and four sulphur positions. The crystal structure consists of blocks of diagonal chains of four octahedra M1 Bi/Ag/Sb) - M2 (Sb/Pb/Bi) - M2 - M1 separated by Pb atoms in bicapped trigonal prismatic coordination of the site M3. The structure is similar to that of Ag-free lillianite.
