The material structure described by Gd2Al3Ge4 crystallizes in the orthorhombic Cmce space group. Gd(1) is bonded in a 14-coordinate geometry to two equivalent Al(1), four equivalent Al(2), four equivalent Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 6-coordinate geometry to four equivalent Gd(1), two equivalent Ge(2), and four equivalent Ge(1) atoms. In the second Al site, Al(2) is bonded in a 5-coordinate geometry to four equivalent Gd(1), one Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent Gd(1), one Al(2), two equivalent Al(1), and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to four equivalent Gd(1), one Al(1), and four equivalent Al(2) atoms. is represented by the CIF card [CIF]
