MS-86: Modular structure of inorganic and mineral compounds
Invited: Olivier Perez (France), Marie Colmont (France) | ||
| Session Abstract | ||
|
Modular structures are built of distinct layers, rods or blocks, which can be arranged in different ways. They are ubiquitously found in the realms of synthetic inorganic chemistry as well as mineral compounds and lead to challenging crystallographic problems, such a twinning, allotwinning or diffuse | ||
