Zr Ta Ta Rh
ZrTa2Rh is beta Plutonium-derived structured and crystallizes in the monoclinic Cm space group. Zr(1) is bonded in a 9-coordinate geometry to four equivalent Ta(1), four equivalent Ta(2), and two equivalent Rh(1) atoms. There are a spread of Zr(1)-Ta(1) bond distances ranging from 1.98-2.92 Å. There are a spread of Zr(1)-Ta(2) bond distances ranging from 1.83-2.82 Å. There is one shorter (3.32 Å) and one longer (3.74 Å) Zr(1)-Rh(1) bond length. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 2-coordinate geometry to four equivalent Zr(1), one Ta(2), and three equivalent Rh(1) atoms. The Ta(1)-Ta(2) bond length is 1.35 Å. There is one shorter (3.36 Å) and two longer (3.69 Å) Ta(1)-Rh(1) bond lengths. In the second Ta site, Ta(2) is bonded in a 2-coordinate geometry to four equivalent Zr(1), one Ta(1), and three equivalent Rh(1) atoms. There is one shorter (3.36 Å) and two longer (3.69 Å) Ta(2)-Rh(1) bond lengths. Rh(1) is bonded in a 12-coordinate geometry to two equivalent Zr(1), three equivalent Ta(1), three equivalent Ta(2), and four equivalent Rh(1) atoms. All Rh(1)-Rh(1) bond lengths are 3.22 Å.
