Nous avons affine la structure cristalline de l'uzonite provenant localite type, caldeira Uzon, au Kamchatka, en Russie, dans le groupe spatial P2 1 /m jusqu'a un residu R 2.66%. Les parametres reticulaires sont: a 7.973(2), b 8.096(2), c 7.148(2) A, β 101.01(2)°, V 452.9(2) A 3 , Z = 2. Le modele structural propose anterieurement pour l'analogue synthetique ete confirme, tout atteignant une precision plus elevee. La contient des molecules distinctes As 4 S 5 liaisons covalentes, retenues...
Alacranite from the type locality (Uzon caldera, Kamchatka, Russian Federation) was submitted for structural analysis. A single crystal selected and following lattice parameters were determined: a = 9.942(4), b 9.601(2), c 9.178(3) Å, β 101.94(3)°, V 857.1 (5) Å3. The structure solved in P2/c space group using direct methods refined to R 6.79% 472 observed reflections. of alacranite consists an ordered sequence As4S4 As4S5 cage-like molecules, with molecular packing closely resembling that...
