Diamond cubic - Wikipedia

Diamond''s cubic structure is in the Fd 3 m space group, which follows the face-centered cubic Bravais lattice.The lattice describes the repeat pattern; for diamond cubic crystals this lattice is "decorated" with a motif of two tetrahedrally bonded atoms in each primitive cell, separated by 1 / 4 of the width of the unit cell in each dimension.
