In crystallography, a primitive unit cell is the smallest repeating unit that, by pure translation, can generate the entire crystal lattice. There are seven primitive unit cells corresponding to the seven crystal systems. The cubic primitive unit cell has all edges equal, a = b = c, and all interaxial angles α = β = γ = 90°. Its lattice points are located only at the eight corners of the cube. ``` •────• │ │ │ __________ ___ ________ ___ ______ _______ __________.
