Figure 4
Construction of the 2∞[Te2O5]2− layers in other MIITe2O5 structures. The Te atoms are displayed as shaded spheres and the O atoms as open spheres. Short Te—O bonds of less than 2.20 Å are drawn with solid bonds and longer Te—O bonds are drawn with open bonds. Crystal data for M = Mg, Ni and Cu were taken from Weil (2005), Platte & Trömel (1981) and Hanke et al. (1973), respectively. |
