Y Y Ta Rh
Y2TaRh crystallizes in the monoclinic Cm space group. Y(1) is bonded in a distorted linear geometry to one Ta(1) and one Rh(1) atom. The Y(1)-Ta(1) bond length is 2.28 Å. The Y(1)-Rh(1) bond length is 2.08 Å. Ta(1) is bonded in a distorted see-saw-like geometry to two equivalent Y(1) and two equivalent Rh(1) atoms. There is one shorter (2.25 Å) and one longer (2.72 Å) Ta(1)-Rh(1) bond length. Rh(1) is bonded in a 4-coordinate geometry to two equivalent Y(1) and two equivalent Ta(1) atoms.
