Реферат:	eng: An X-ray diffraction study of mineral livingstonite (HgSb4S 8) from Khaydarkan (Kyrgyzstan) has been performed on a Bruker Nonius X8Apex diffractometer with a 4K CCD detector (R = 0.031). The unit-cell parameters were found to be a = 30.1543(10) Å, b = 3.9953(2) Å, c = 21.4262(13) Å, β = 104.265(1)°, V = 2501.7(2) Å3, Z = 8, d calcd = 5.013 g/cm3, and sp. gr. A2/a. It was confirmed that livingstonite belongs to rod-layers structures. In one type of layer, two double Sb2S4 chains are bound by disulfide groups [S2]2- (S-S 2.078(2) Å); in the other type, these chains are bound via Hg2+ cations. A crystallographic analysis confirmed the existence of independent pseudotranslational ordering in the cation and anion matrices, which is characteristic of the lozenge-like structures of sulfides and sulfosalts. © 2010 Pleiades Publishing, Ltd.
