What is packing polymorphism
When polymorphism exists as a result of change in crystal packing, it is called packing polymorphism. Polymorphism can also result from the existence of dissimilar conformers of the similar molecule in conformational polymorphism. In pseudopolymorphism the dissimilar crystal types are the result of hydration or solvation. An example of an organic polymorph is glycine, which is able to form monoclinic and hexagonal crystals. Silica is known to form many polymorphs, the most significant of which are; α-quartz, β-quartz, tridymite, cristobalite, coesite, and stishovite.
