Efficient Packing
The crystal structures of ionic solids composed solely of monatomic ions is governed by two relatively simple factors.
The most efficient packing of the ions is desired.
Because like charges repel, it is necessary to prevent two anions or two cations from coming in contact with each other.
Just as covalent bonding and non-spherical atoms created exceptions to the closest-packing rule for metals, these same issues can be important in the packing of ionic solids. Consequently there are many exceptions to the simple rules discussed here.
