Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...

The face centered cubic (FCC) unit cell begins with a totally different layer, one that is packed much more efficiently. This figure shows the basic layer that will be repeated throughout the entire ...

Since the stoichiometry of the salt is 2:1, we must fill all of the tetrahedral holes (the FCC structure gives four selenides, thus we need eight lithiums). will occupy the latice points that define ...

Specifically, NaCl forms a “face-centered cubic” (FCC) lattice structure. In this configuration, each sodium ion is ...
