Figure 3
A view of (III), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level and H atoms are shown as small spheres of arbitrary radii. The minor components of disordered atoms O51/O61/C231/C241 of the hemifumaric acid molecule have been omitted for clarity. The dashed lines indicate hydrogen bonds.
