Polymorphs are fascinating because they represent special cases where the delicate balance between intra-crystal interactions gives rise to alternative results. Investigation of polymorphism provides some insight into the subtle interplay between the forces involved. An understanding of such interactions and the resulting structural patterns is clearly a prerequisite to materials design.

Of particular interest is reactivity in the solid state, with the ideal process occurring in crystalline materials. The results can be starkly different in comparison to reactions in the fluid state; for example, unique products may be obtained in pure form, i.e. uncontaminated by impurities or solvents.   A distinct product may also be obtained for each form in polymorphic systems. An aim of the research in this area is to understand and subsequently control the crystallisation process in order to influence the reaction products.
