ABSTRACT
McKie and McKie (1986), Prince (2004), Senechal (1990), Stróz (2003), Tiekink and Vittal (2006), Tilley (2006), and Zachariasen (1967).
In this book, the crystallographic ideas are rst developed in two dimensions for clarity, simplicity, and overall understanding. Later, the transition to three dimensions is made. roughout the rst seven chapters of this book computer-based calculations are done on three study crystals: hexamethylbenzene, C6(CH3)6, (HMB); anhydrous alum, KAl(SO4)2, (AA); and caeine monohydrate. HMB is a relatively small molecule. In this book, it is considered to be a prototype of a polymer because it has two types of bonding, covalent bonds within the molecule and weaker van der Waals bonds between molecules. AA is an ionic framework structure typically found in ceramics. Caeine monohydrate with more atoms per unit cell is more complex than either HMB or AA. See Section 4.14. ese three crystals have complementary crystallographic features.
