Figure 2
Part of the crystal structure of ammonium metavanadate, showing hydrogen bonds as dashed lines. Four vanadate chains are represented with different colours, and the asymmetric unit is indicated with black labels. Hydrogen bonds are labelled (1)–(4), corresponding to entries in Table 2, and the supramolecular rings linking the anions and cations in the crystal are coloured yellow. Displacement ellipsoids are drawn at the 50% probability level. [Symmetry codes: (i) −x + 1, y + , −z + ; (ii) −x + 2, y + , −z + ; (iii) x + 1, −y + , −z.] |
