Abstract

A new vanadium molybdenum mixed oxide V{sub 1.1}Mo{sub 0.9}O{sub 5} [V(V){sub 0.2}V(IV){sub 0.9}Mo(VI){sub 0.9}O{sub 5}] has been synthesized, as a pure phase, via hydrothermal methods in the presence of molybdic acid and vanadyl sulfate. Its crystal structure has been solved ab initio from high-resolution powder diffraction data collected at the ESRF beamline ID31. This compound crystallizes in the monoclinic symmetry, space group C2/m, with cell dimensions a=12.1230(2)A, b=3.7168(1)A, c=4.0336(1)A, {beta}=90.625(3){sup o} and Z=2 per formula. The structure consists of double strings of VO{sub 5} square pyramids sharing edges and corners along [100] and [010], and more weakly bound along [001]. In this latter direction, the bond (V,Mo)-O=2.377A, while remaining long, leads for the first time to the interpenetration of the apical oxygens of the [(V,Mo){sub 2}O{sub 5}]{sub n} layers, resulting in a three-dimensional (3D) structure closely related to R-Nb{sub 2}O{sub 5}. This structure will be compared to the pure layer structure of V{sub 2}O{sub 5} where this bond reaches 2.793A.

The atomic-scale characterization of defects on cleaved vanadium and molybdenum oxide surfaces using STM

Conference Rohrer, G; Smith, R

Scanning tunneling microscopy (STM) was used to determine the structure of cleaved, single crystal surfaces of V{sub 2}O{sub 5}, V{sub 6}O{sub 13}, Mo{sub 18}O{sub 52}, and Mo{sub 8}O{sub 23}. Constant current images were recorded in ultrahigh vacuum and in air. By imaging well-defined surfaces that exhibit structural and chemical similarities, and comparing the observations to the know bulk structures, it is possible to establish a reliable interpretation for the contrast in the STM images. A comparison of images from the V{sub 6}O{sub 13}(001) and the V{sub 2}O{sub 5}(001) surfaces clearly shows that the surface V coordination polyhedra that are cappedmore »« less
