Figure 7
A partial packing view of (III), showing two hexameric [R66(30) and R66(24)] hydrogen-bonded networks. Hydrogen bonds are shown as dashed lines and H atoms not involved in hydrogen bonding and the minor components of disordered atoms O51/O61/C231/C241 of the hemifumaric acid molecule have been omitted for clarity. Only atoms involved in hydrogen bonding are labelled. [Symmetry codes: (i) −x, −y + 1, −z; (ii) −x + 1, −y + 1, −z + 1.] |
