The structure described by GdNi3Al9 crystallizes in the trigonal R32 space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 17-coordinate geometry to six equivalent Ni(1), one Al(1), one Al(6), three equivalent Al(2), and six equivalent Al(4) atoms. In the second Gd site, Gd(1) is bonded in a 17-coordinate geometry to six equivalent Ni(1), one Al(1), one Al(6), three equivalent Al(2), and six equivalent Al(4) atoms. Ni(1) is bonded in a 8-coordinate geometry to two Gd(1,1); one Al(1); one Al(2); one Al(3); one Al(5); one Al(6); and three equivalent Al(4) atoms. There are six inequivalent Al sites. In the first Al site, Al(1) is bonded in a distorted trigonal non-coplanar geometry to one Gd(1), three equivalent Ni(1), one Al(1), three equivalent Al(3), and three equivalent Al(4) atoms. In the second Al site, Al(2) is bonded in a 10-coordinate geometry to two Gd(1,1); two equivalent Ni(1); two equivalent Al(2); and four equivalent Al(4) atoms. In the third Al site, Al(3) is bonded in a linear geometry to two equivalent Ni(1), two equivalent Al(1), two equivalent Al(5), and two equivalent Al(6) atoms. In the fourth Al site, Al(4) is bonded in a 3-coordinate geometry to two Gd(1,1); three equivalent Ni(1); one Al(1); one Al(5); one Al(6); and two equivalent Al(2) atoms. In the fifth Al site, Al(5) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ni(1), one Al(6), three equivalent Al(3), and three equivalent Al(4) atoms. In the sixth Al site, Al(6) is bonded in a distorted trigonal non-coplanar geometry to one Gd(1), three equivalent Ni(1), one Al(5), three equivalent Al(3), and three equivalent Al(4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
