Ta B Rh Rh
TaRh2B crystallizes in the triclinic P1 space group. Ta(1) is bonded in a 2-coordinate geometry to two equivalent Rh(1) and two equivalent B(1) atoms. There is one shorter (2.85 Å) and one longer (3.07 Å) Ta(1)-Rh(1) bond length. There is one shorter (1.95 Å) and one longer (2.29 Å) Ta(1)-B(1) bond length. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 8-coordinate geometry to two equivalent Ta(1), four equivalent Rh(2), and two equivalent B(1) atoms. There are a spread of Rh(1)-Rh(2) bond distances ranging from 1.58-2.82 Å. There is one shorter (2.33 Å) and one longer (2.62 Å) Rh(1)-B(1) bond length. In the second Rh site, Rh(2) is bonded in a 1-coordinate geometry to four equivalent Rh(1) and one B(1) atom. The Rh(2)-B(1) bond length is 1.72 Å. B(1) is bonded in a 3-coordinate geometry to two equivalent Ta(1), one Rh(2), and two equivalent Rh(1) atoms.
