Structures of ionic solids may be understood in terms of the packing of spheres, whereas molecular crystals result from the packing of diverse shapes.The main types of crystalline solids are ionic solids, metallic solids, covalent network solids, and molecular solids.
Molecular crystals are substances that have relatively weak intermolecular binding, such as dry ice (solidified carbon dioxide), solid forms of the noble gases (e.g., argon, krypton, and xenon), and crystals of numerous organic compounds.
