β-SulfurThe structure to the left shows that the unit cell takes up two neighbouring segments of the six segments within the sulfide hexagonal layer structure. One of these segments contains another sulfide ion (compare with page 5 of magnesium to see how these are related).
Go to page 5 to consider the holes in the structure.
