Sr2NbCd crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Sr2NbCd cluster. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one Nb(1) atom. The Sr(1)-Nb(1) bond length is 0.94 Å. In the second Sr site, Sr(2) is bonded in a single-bond geometry to one Nb(1) and one Cd(1) atom. The Sr(2)-Nb(1) bond length is 0.47 Å. The Sr(2)-Cd(1) bond length is 0.12 Å. Nb(1) is bonded in a 3-coordinate geometry to one Sr(1), one Sr(2), and one Cd(1) atom. The Nb(1)-Cd(1) bond length is 0.46 Å. Cd(1) is bonded in a single-bond geometry to one Sr(2) and one Nb(1) atom.
