This single layer is the precursor of the simple cubic (SC) unit cell. The lattice points are touching one another but not in the most efficient way. In other words, we are creating a lot of empty ...

This single layer is the precursor of the body centered cubic (BCC) unit cell. The lattice points are in the same general form as the simple cubic (SC) unit cell, with the exception that the atoms are ...

The monoclinic structure has two unit cells. The primative cell (P) has fractional lattice points at the corners of the cell, and the base-centered cell (C) has additional fractional lattice points at ...
