Figure 1
Crystal structure of (NH4)2V3O8 viewed approximately down the c axis. The asymmetric unit is represented with displacement ellipsoids drawn at the 90% probability level, and other vanadate groups are drawn with a polyhedral representation. Only one (V3O8)2– layer normal to [001] is represented, and a single position for the disordered NH4+ cation has been accentuated. Blue planes are the mirror m elements of space-group type P4bm. |
