Title: The crystal structure of the cesium molybdenum bronze Cs[sub 0. 14]MoO[sub 3]

The crystal of the title compound is hexagonal, space group P6[sub 3]/m, with a = 10.620(9), c = 3.722(2) [angstrom], and Z = 6. Couples of MoO[sub 6] distorted octahedra, linked by edges, constitute, by repetitive edge sharing along the c axis, ribbons kept together in bundles by lateral corner sharing. These bundles, by being packed together, generate tunnels where delocalized Cs atoms are inserted. The results confirmed the previously found correlation between the Mo oxidation state and the distortion of the coordination [open quotes]octahedra[close quotes] and allow one to extend the correlation to the possible conduction properties of the title compound and to those of structurally related oxides and bronzes. 13 refs., 4 figs., 3 tabs.
