Holes in Anion Arrays

Summary:

The structures of many simple ionic solids result from the packing of positive ions (cations) in holes in an array of negative ions (anions).

Tetrahedral and octahedral holes are found in close packed arrays of anions.

Cubic holes are found in simple arrays of anions.
