Figure 3 The alternate polyanion stacking of A-type and B-type viewed along the c axis. The square shows the unit cell. The MoO6 octahedron is denoted in open faced manner, and the O atoms in the CoMo6 polyanion are denoted by red spheres. The definition of the least square plane consisting of Co, Mo1, Mo2, Mo3, Mo4, Mo5, and Mo6 in the CoMo6 polyanion is also represented. |
