β-SulfurThe image to the left shows the yellow wireframe unit cell from the last page in isolation. In order to make it easier to see that it is equivalent to the unit cell shown on page 3, the yellow wireframe cube from the last page has been rotated clockwise by 90 degrees. You can see that the atom positions of the different types of ion have been exchanged compared to the unit cell on page 3.
Go to page 9 to consider the conformation of six-membered rings in the zinc blende structure.
