Tetrahedral and octahedral sites in closest packing can be occupied by other atoms or ions in crystal structures of salts and alloys. ... Whenever you put four (4) spheres together touching each other, you've got a tetrahedral arrangement of spheres. The space in the center is called a tetrahedral site...

When 4 spherical atoms are in a closely packed arrangement, the empty gap remaining in between the spheres is called a Tetrehdral site or void.
When 6 spherical atoms, 3 in one layer and 3 in another are in a closely packed arrangement, the empty gap remaining in between the spheres is called an Octahedral site or void.
- Suppose there are 3 spheres touching each other in one layer. If another sphere is placed on top of this layer such that it is touching all the three spheres, the empty site in between these spheres is called the Tetrahedral site as the formation of the spheres looks like a tetrahedral.
- Suppose there are 3 spheres touching each other in one layer. If another 3 spheres in one layer are placed on top of this layer, the empty site in between these spheres formed by the combination of two triangular voids is called an Octahedral site as the formation of the spheres looks like an Octahedron as the spheres are on the vertices of a regular Octahedron.
