WCdAl4 crystallizes in the trigonal R3m space group. W(1) is bonded in a 7-coordinate geometry to one Cd(1), three equivalent Al(1), and three equivalent Al(2) atoms. The W(1)-Cd(1) bond length is 2.17 Å. All W(1)-Al(1) bond lengths are 1.89 Å. All W(1)-Al(2) bond lengths are 3.14 Å. Cd(1) is bonded in a distorted trigonal pyramidal geometry to one W(1) and three equivalent Al(1) atoms. All Cd(1)-Al(1) bond lengths are 2.49 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 5-coordinate geometry to one W(1), one Cd(1), one Al(2), and two equivalent Al(1) atoms. The Al(1)-Al(2) bond length is 1.51 Å. Both Al(1)-Al(1) bond lengths are 0.87 Å. In the second Al site, Al(2) is bonded in a 6-coordinate geometry to three equivalent W(1) and three equivalent Al(1) atoms.
