New applications and design processes in crystal engineering are described in the nine papers of this volume, which were written by groups of chemists and engineers in the US, Canada, the UK, Japan, France, Switzerland, Italy, and the Netherlands. The chapter titles include: applications to crystal design of hydrogen bonds in inorganic chemistry, molecular recognition and self-assembly between amines and alcohols, very large supramolecular capsules based on hydrogen bonding, crystal transformations and gas-solid reactions, and solid-gas interactions between small gaseous molecules and transition metals in the solid state. Each paper features the authors' own research and includes an exhaustive bibliography. The papers are well illustrated with b&w and some color plates.
