Relationship between the [Fd{\overline 3}m] unit cell (a ≃ 19.4 Å, displayed in black) and the monoclinic A2/n cell (a′ = c′ ≃ 23.7 Å and b′ ≃ 13.7 Å, in blue; analogous C2/c setting in green). The identical lattice points of the cubic F lattice and the monoclinic A lattice are marked by yellow spheres. Gray spheres in the [Fd{\overline 3}m] cell lose translation identity in A2/n and C2/c.
