Figure 2
A [001] projection of the average structure. This projection is drawn assuming a perfect hexagonal close packing for the O atoms (idealized structure) and only one (001) metallic layer (at z centred at 1/2) is shown. The adjacent (001) metallic layer (at z = 0) is obtained from this layer by a shift of a/2 (or b/2). The octahedral Mo6 units are outlined and the three independent Mo atoms are shown by numbers. The expected metallic bonds between the Mo6 unit and Mo (or V) likely to occupy the Mo(4) sites surrounding this metal octahedron are drawn with dotted lines. The Eu—O and Mo—O bonds are also indicated (dashed lines). The symbols l and n denote the possible interactions between the clusters within a particular layer.
