NaWCd2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a distorted single-bond geometry to one W(1), one Cd(1), and two equivalent Cd(2) atoms. The Na(1)-W(1) bond length is 1.86 Å. The Na(1)-Cd(1) bond length is 2.52 Å. There is one shorter (3.05 Å) and one longer (3.21 Å) Na(1)-Cd(2) bond length. W(1) is bonded in a single-bond geometry to one Na(1), one Cd(1), and one Cd(2) atom. The W(1)-Cd(1) bond length is 2.97 Å. The W(1)-Cd(2) bond length is 2.97 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 3-coordinate geometry to one Na(1), one W(1), and one Cd(2) atom. The Cd(1)-Cd(2) bond length is 1.86 Å. In the second Cd site, Cd(2) is bonded in a 6-coordinate geometry to two equivalent Na(1), one W(1), one Cd(1), and two equivalent Cd(2) atoms. Both Cd(2)-Cd(2) bond lengths are 2.74 Å.
