(color online) The transition from the bcc structure (Im-3m) to a rhombohedral structure (R-3m). The bcc unit cell is depicted by the black lines. The rhombohedral unit cell is framed with basis vectors a 1 , a 2 , and a 3 , corresponding to the vectors in the [11-1], [-110], and [111] directions, respectively.
