Unit Cells - Purdue University

Unit Cells: NaCl and ZnS. NaCl should crystallize in a cubic closest-packed array of Cl-ions with Na + ions in the octahedral holes between planes of Cl-ions. We can translate this information into a unit-cell model for NaCl by remeering that the face-centered cubic unit cell is the simplest repeating unit in a cubic closest-packed structure.
