The structure described by GdAl crystallizes in the orthorhombic Cmcm space group. Gd(1) is bonded in a 8-coordinate geometry to four equivalent Al(1) and four equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to eight equivalent Gd(1), two equivalent Al(1), and two equivalent Al(2) atoms to form a mixture of corner, face, and edge-sharing AlGd8Al4 cuboctahedra. In the second Al site, Al(2) is bonded in a 10-coordinate geometry to eight equivalent Gd(1) and two equivalent Al(1) atoms. is represented by the CIF file [CIF]
