Figure 1
Part of the crystal structure of ammonium metavanadate, viewed approximately down [100], using a polyhedral representation for the vanadate chains and spheres of arbitrary radii for ammonium cations (Boudias & Monceau, 1998). The inset shows non-H atoms with displacement ellipsoids at the 80% probability level. The V1′ and O3′ sites are generated by the symmetry operations x, − y, −z and x, y, − z, respectively. |
