The effect of pressure on a number of different classes of molecular crystal structures has been investigated, including very simple compounds such as acetone and pyridine, ligands used in metal extraction, amino acids and metal complexes. Work in the organic solid state has largely focussed on phase transitions, and efforts to understand the competing factors which control these transitions will be described. Intramolecular bond distances and angles are usually not greatly affected in organic solids, but the same is not true in coordination complexes, where metal geometry is much more flexible. The talk will also describe how this feature makes high-pressure an extremely useful tool for exploring structure-property relationship in coordination materials.
