Figure 2
View of the framework structure of (a) AgAl(HAsO4)2 along [101] and (b) isotypic AgGa(HAsO4)2 along [110]. The M3+O6 octahedra (M = Al, Ga) are corner-linked to HAsO4 tetrahedra. Both views show small micropores in which the Ag+ cations are situated; the split Ag position (see text) and hydrogen bonds (dashed lines) are indicated in (b). |
