Some ionic lattices
A lattice of chloride ions Cl-
The cesium ions Cs+, too big, do not find a place among the Cl- ions in a two-dimensional layer
We see that a centered cubic lattice is about to form.
The centered cubic arrangement continues to form ...
Check the structure to observe that Cs+ ions and Cl- ions occupy centers of cubes!
