Figure 3
A view of the cation and anion in (II), showing the atom-labelling scheme. Unlabelled atoms are generated by the symmetry operation (−x, −y + 2, −z). Displacement ellipsoids are drawn at the 30% probability level. Hydrogen bonds are denoted by dashed lines. R22(8) and R21(6) graph-set motifs are formed (Etter et al., 1990). |
