Figure 7
The crystal structure of β-V2O5 projected along [010] in (a)–(c). The two layers at y = ¼ and y = ¾ are shown in (b) and (c). The layers are connected by edge-sharing along b. The arrows denote a possible tilt of the pairs in the strings from β to B. The crystal structure of B-Ta2O5 is projected along [010] in (d)–(f). The two layers at y = ¼ and y = ¾ are shown in (e) and (f). The layers are mutually linked by corner-sharing so that rutile-like slabs are formed; see (d). |
