TaRh2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. Ta(1) is bonded in a 10-coordinate geometry to five equivalent Rh(1) and five equivalent Rh(2) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 5-coordinate geometry to five equivalent Ta(1) atoms. In the second Rh site, Rh(1) is bonded in a 5-coordinate geometry to five equivalent Ta(1) atoms.
TaRh2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. Ta(1) is bonded in a 10-coordinate geometry to five equivalent Rh(1) and five equivalent Rh(2) atoms. There are a spread of Ta(1)-Rh(1) bond distances ranging from 2.66-2.84 Å. There are two shorter (2.66 Å) and three longer (2.78 Å) Ta(1)-Rh(2) bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh(2) is bonded in a 5-coordinate geometry to five equivalent Ta(1) atoms. In the second Rh site, Rh(1) is bonded in a 5-coordinate geometry to five equivalent Ta(1) atoms.
