(Na)2TiCd crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two disodium molecules and two TiCd clusters. In each TiCd cluster, Ti(1) is bonded in a single-bond geometry to one Cd(1) atom. The Ti(1)-Cd(1) bond length is 0.98 Å. Cd(1) is bonded in a single-bond geometry to one Ti(1) atom.
