The science of the arrangement of atoms in solids is known as crystallography. In single crystals, the effects of the crystalline arrangement of atoms is often easy to see macroscopically, because the natural shapes of crystals reflect the atomic structure. In addition, physical properties are often controlled by crystalline defects. The understanding of crystal structures is an important prerequisite for understanding crystallographic defects. Topics discussed in this new book include in situ protein crystal diffraction screening; structures and properties of 3D-4F and 3D chiral Schiff base complexes; crystal dehydration techniques; case studies on crystal structure determination involving H atoms; and cleavage fracture crystallography.
