Dear Student,
 
A three-dimensional network of an ionic compound is termed as "ionic crystal lattice" or "ionic crystal structure".
In an ionic crystal lattice or ionic crystal structure, positively charged ions (cations) and negatively charged ions (anions) are arranged in a repeating, three-dimensional pattern held together by electrostatic forces of attraction.
For example: sodium chloride or NaCl is the ionic crystal lattice of sodium cations and chloride anions.
