Solution: The structures of CsCl, NaCl, and ZnS. Each structure type can be generated by the combination of a two-atom motif and the appropriate lattice.If not, which ions do touch each other?

Problem

Motif plus crystal lattice leads to crystal structure. A cesium-chloride crystal has chlorine and cesium touching on a diagonal. Cesium-chloride crystal lattice is primitive cubic, a cube with lattice points at the corners. Chlorine atoms form the corners of the cube and cesium is in the center of the cube. Sodium-chloride crystals have sodium and chlorine touching horizontally.  Sodium-chloride crystal lattice is face-centered cubic, a cube with lattice points at the corners and in the center of each face. The sodium-chloride cube consists of 3 layers, each layer consisting of rows of alternating sodium and chlorine ions.  Zinc-sulfur crystal has zinc and sulfur touching on a diagonal.  Zinc-sulfur crystal lattice is face-centered cubic, a cube with lattice points at the corners and in the center of each face.  Sulfur atoms form the corners and are at the center of each face and zinc atoms are in the center.
