Restraining stereochemistry of chemical links to symmetry-related molecules (~1992) 18.7.5.6. Restraining stereochemistry of chemical links to symmetry-related molecules (~1992) It is not uncommon for crystallization enhancers to be found on a special position in the crystal. In addition, cross-linking the molecules in a crystal is often done for ...
