AlAs is High Pressure Cadmuum Telluride structured and crystallizes in the tetragonal P4/mmm space group. Al(1) is bonded to four equivalent Al(1) and two equivalent As(1) atoms to form distorted AlAl4As2 octahedra that share corners with six equivalent Al(1)Al4As2 octahedra, edges with four equivalent Al(1)Al4As2 octahedra, and edges with eight equivalent As(1)Al2As4 octahedra. The corner-sharing octahedra are not tilted. As(1) is bonded to two equivalent Al(1) and four equivalent As(1) atoms to form distorted AsAl2As4 octahedra that share corners with six equivalent As(1)Al2As4 octahedra, edges with four equivalent As(1)Al2As4 octahedra, and edges with eight equivalent Al(1)Al4As2 octahedra. The corner-sharing octahedra are not tilted.
