WebJun 10, 2024 · CsCl is an ionic compound that can be prepared by the reaction: (12.3B.1) Cs 2 CO 3 + 2 HCl 2 CsCl + H 2 O + CO 2. Figure 12.3 B. 1: CsCl Coordination Cubes. (Public Domain; Solid State via Wikipedia) CsCl crystallize in a primitive cubic lattice which means the cubic unit cell has nodes only at its corners.
In crystallography, atomic packing factor (APF), packing efficiency, or packing fraction is the fraction of volume in a crystal structure that is occupied by constituent particles. It is a dimensionless quantity and always less than unity. In atomic systems, by convention, the APF is determined by assuming that atoms are rigid spheres. The radius of the spheres is taken to be the maximum value such that the atoms do not overlap.
