Ta B B Rh
TaRhB2 crystallizes in the triclinic P1 space group. Ta(1) is bonded in a 10-coordinate geometry to two equivalent Rh(1), four equivalent B(1), and four equivalent B(2) atoms. There is one shorter (2.35 Å) and one longer (2.49 Å) Ta(1)-Rh(1) bond length. There are a spread of Ta(1)-B(1) bond distances ranging from 2.01-2.63 Å. There are a spread of Ta(1)-B(2) bond distances ranging from 2.01-2.63 Å. Rh(1) is bonded in a 5-coordinate geometry to two equivalent Ta(1), one B(2), and two equivalent B(1) atoms. The Rh(1)-B(2) bond length is 2.60 Å. There is one shorter (1.76 Å) and one longer (2.29 Å) Rh(1)-B(1) bond length. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 7-coordinate geometry to four equivalent Ta(1), two equivalent Rh(1), and one B(2) atom. The B(1)-B(2) bond length is 1.29 Å. In the second B site, B(2) is bonded in a 6-coordinate geometry to four equivalent Ta(1), one Rh(1), and one B(1) atom.
