Y Y Ta Cd
Y2TaCd is alpha Niobium phosphide-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Y2TaCd cluster. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a distorted single-bond geometry to one Ta(1) and one Cd(1) atom. The Y(1)-Ta(1) bond length is 1.73 Å. The Y(1)-Cd(1) bond length is 0.99 Å. In the second Y site, Y(2) is bonded in a distorted single-bond geometry to one Ta(1) atom. The Y(2)-Ta(1) bond length is 1.60 Å. Ta(1) is bonded in a 2-coordinate geometry to one Y(1) and one Y(2) atom. Cd(1) is bonded in a single-bond geometry to one Y(1) atom.
