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. The diamond lattice can be viewed as a pair of

GaAs is Zincblende, Sphalerite structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. Ga3+ is bonded to four equivalent As3- atoms to form corner-sharing GaAs4 tetrahedra. All Ga–As bond lengths are 2.49 Å. As3- is bonded to four equivalent Ga3+ atoms to form corner-sharing AsGa4 tetrahedra.
