摘要: An X-ray diffraction study of mineral livingstonite (HgSb4S8) from Khaydarkan (Kyrgyzstan) has been performed on a Bruker Nonius X8Apex diffractometer with 4K CCD detector (R = 0.031). The unit-cell parameters were found to be 30.1543(10) A, b 3.9953(2) c 21.4262(13) β 104.265(1)°, V 2501.7(2) A3, Z 8, dcalcd 5.013 g/cm3, and sp. gr. A2/a. It was confirmed that belongs rod-layers structures. In one type layer, two double Sb2S4 chains are bound by disulfide groups [S2]2− (S-S 2.078(2) A); in the other type, these via Hg2+ cations. A crystallographic analysis existence independent pseudotranslational ordering cation anion matrices, which is characteristic lozenge-like structures sulfides sulfosalts.
