TbPdAs crystallizes in the orthorhombic Pnma space group. Tb(1) is bonded in a 11-coordinate geometry to six equivalent Pd(1) and five equivalent As(1) atoms. Pd(1) is bonded in a 12-coordinate geometry to six equivalent Tb(1), two equivalent Pd(1), and four equivalent As(1) atoms. As(1) is bonded in a 9-coordinate geometry to five equivalent Tb(1) and four equivalent Pd(1) atoms.
TbPdAs crystallizes in the orthorhombic Pnma space group. Tb(1) is bonded in a 11-coordinate geometry to six equivalent Pd(1) and five equivalent As(1) atoms. There are a spread of Tb(1)-Pd(1) bond distances ranging from 3.04-3.39 Å. There are three shorter (2.92 Å) and two longer (2.99 Å) Tb(1)-As(1) bond lengths. Pd(1) is bonded in a 12-coordinate geometry to six equivalent Tb(1), two equivalent Pd(1), and four equivalent As(1) atoms. Both Pd(1)-Pd(1) bond lengths are 3.08 Å. There are a spread of Pd(1)-As(1) bond distances ranging from 2.62-2.84 Å. As(1) is bonded in a 9-coordinate geometry to five equivalent Tb(1) and four equivalent Pd(1) atoms.
