Реферат: | eng: The crystal structure of laffittite mineral AgHg(As,Sb)S3 from the Chauvai deposit (Kyrgyzstan), containing about 10% of Sb atoms in the As3+ position, is re-determined (Aa space group, a = 7.7560(3) Å, b = 11.3340(4) Å, c = 6.6650(3) Å, β = 115.233(4)°, V =529.99(4) Å3, d = 6.078 g/cm3, Z = 4, R = 0.0229). Crystallographic analysis of the structure reveales the presence of quite regular face-centered cubic cation and anion sublattices, thus confirming the assignment of the structure to the structural type of PbS. A deviation from the octahedral coordination of cations characteristic of this type is mainly related to a mutual asymmetric displacement of the cation and anion matrices. © 2010 Pleiades Publishing, Ltd.
