NaYCd2 is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three NaYCd2 clusters. Na(1) is bonded in a distorted single-bond geometry to one Cd(1) atom. The Na(1)-Cd(1) bond length is 2.39 Å. Y(1) is bonded in a distorted linear geometry to one Cd(1) and one Cd(2) atom. The Y(1)-Cd(1) bond length is 2.39 Å. The Y(1)-Cd(2) bond length is 2.39 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a linear geometry to one Na(1) and one Y(1) atom. In the second Cd site, Cd(2) is bonded in a 1-coordinate geometry to one Y(1) atom.
