Figure 3
Fragments of the crystal structures of phases (I) (a and b) and (II) (c and d) of a glutaric acid–glycine co-crystal. Symmetry-independent molecules are shown by different colours. H atoms which are not involved in hydrogen bonds and are hanging contacts are omitted for clarity. The result of overlaying the two glutaric acid molecules with different conformations in phase (II) is shown in (e). |
