Figure 4
PDF with magnification of the local part r < 9 Å (gray area); all given distances are in Å. Corresponding distances of edge-sharing CrTe6 octahedra are depicted on the right (view onto the b–c plane). Peak A represents Cr–Te bonds of CrTe6 octahedra. Inset top left: schematic view onto the a–c plane. Included are Cr–Cr distances corresponding to peak D that could not be marked in the view on the right. Included in peak D are also short Te–Te distances interconnecting the chains of edge-sharing octahedra (yellow). They are short, only 2.78 Å (r ∼ D/2), indicating the presence of Te22− polyanions (Canadell et al., 1992). |
