The structure described by Gd(CrAl)6 crystallizes in the orthorhombic Immm space group. Gd(1) is bonded in a 20-coordinate geometry to four equivalent Cr(2), eight equivalent Cr(1), two equivalent Al(1), two equivalent Al(2), and four equivalent Al(3) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to two equivalent Gd(1), two equivalent Cr(1), two equivalent Cr(2), two equivalent Al(1), two equivalent Al(2), and two equivalent Al(3) atoms to form a mixture of distorted edge, corner, and face-sharing CrGd2Al6Cr4 cuboctahedra. In the second Cr site, Cr(2) is bonded to two equivalent Gd(1), four equivalent Cr(1), two equivalent Al(1), two equivalent Al(2), and two equivalent Al(3) atoms to form a mixture of distorted edge, corner, and face-sharing CrGd2Al6Cr4 cuboctahedra. There are three inequivalent Al sites. In the first Al site, Al(1) is bonded in a 10-coordinate geometry to one Gd(1), two equivalent Cr(2), four equivalent Cr(1), one Al(1), and two equivalent Al(3) atoms. In the second Al site, Al(2) is bonded in a 7-coordinate geometry to one Gd(1), two equivalent Cr(2), four equivalent Cr(1), and two equivalent Al(3) atoms. In the third Al site, Al(3) is bonded in a 12-coordinate geometry to two equivalent Gd(1), two equivalent Cr(2), four equivalent Cr(1), two equivalent Al(1), and two equivalent Al(2) atoms. is represented by the CIF card [CIF]
