NaCdZn4 crystallizes in the trigonal R3m space group. Na(1) is bonded in a distorted single-bond geometry to three equivalent Cd(1) and one Zn(2) atom. All Na(1)-Cd(1) bond lengths are 3.08 Å. The Na(1)-Zn(2) bond length is 2.29 Å. Cd(1) is bonded in a 6-coordinate geometry to three equivalent Na(1) and three equivalent Zn(1) atoms. All Cd(1)-Zn(1) bond lengths are 1.32 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 2-coordinate geometry to one Cd(1), one Zn(2), and two equivalent Zn(1) atoms. The Zn(1)-Zn(2) bond length is 1.06 Å. Both Zn(1)-Zn(1) bond lengths are 0.61 Å. In the second Zn site, Zn(2) is bonded in a distorted single-bond geometry to one Na(1) and three equivalent Zn(1) atoms.
