Nearly twenty years ago, Dunitz and Bernstein described a selection of intriguing cases of
polymorphs that disappear. The inability to obtain a crystal form that has previously been …

Many crystalline solids cannot be prepared in the form of single crystals of sufficient size
and/or quality for investigation using single‐crystal X‐ray diffraction techniques, and the …

Most people are familiar with the fact that diamond and graphite are both composed only of
carbon; yet they have very different properties which result from the very different structures …

The art of solving a structure from powder diffraction data has developed rapidly over the last
ten years to the point where numerous crystal structures, both organic and inorganic, have …

Quantum mechanics (QM) approaches (DFT, MP2, CCSD (T), etc.) play an important role in
calculating molecules and crystals with a high accuracy and acceptable efficiency. In recent …
