Darstellung und Kristallstruktur von Antimon(V)oxidhydroxid HSb₃O₈ / Preparation and Crystal Structure of the Antimony(V) Oxide Hydroxide HSb₃O₈

Colourless crystals of HSb 3 O 8 were prepared by hydrothermal methods from Sb 2 O 5 . The crystal structure [P2/n, a = 945.6(2), b = 869.1(2), c = 990.9(2) pm, β = 90.25(2)°, Z = 6. R = 0.045] was determined from diffractometer measurements. Distorted SbO 6 octahedra are linked through vertices and edges to form a three-dimensional polymer of pseudo-orthorhombic symmetry. The hydrogen atoms could not be located.
