Exploring the relationship between cocrystal stability and symmetry: is Wallach's rule applicable to multi-component solids?†
Abstract
Comparison of structure and hydration stability of pairs of chiral and racemic binary cocrystals indicates that the racemic solid is more stable than the chiral one; we illustrate that this difference might arise from intermolecular (crystal packing) factors in one case, while intramolecular (molecular conformation) factors are more significant in the other.
