The material structure described by AlAs is SC16 CuCl, stable at 5GPa structured and crystallizes in the cubic Pa-3 space group. Al(1) is bonded to four equivalent As(1) atoms to form corner-sharing AlAs4 tetrahedra. As(1) is bonded to four equivalent Al(1) atoms to form corner-sharing AsAl4 trigonal pyramids. is represented by the CIF file [CIF]
