Y Y Ta Cd
Y2TaCd crystallizes in the monoclinic Cm space group. Y(1) is bonded in a single-bond geometry to two equivalent Ta(1) and one Cd(1) atom. There is one shorter (2.94 Å) and one longer (2.96 Å) Y(1)-Ta(1) bond length. The Y(1)-Cd(1) bond length is 1.50 Å. Ta(1) is bonded in a 6-coordinate geometry to four equivalent Y(1) and two equivalent Cd(1) atoms. There is one shorter (2.54 Å) and one longer (3.02 Å) Ta(1)-Cd(1) bond length. Cd(1) is bonded in a water-like geometry to two equivalent Y(1) and two equivalent Ta(1) atoms.
