TmPdAs crystallizes in the orthorhombic Pnma space group. Tm(1) is bonded in a 11-coordinate geometry to six equivalent Pd(1) and five equivalent As(1) atoms. Pd(1) is bonded to six equivalent Tm(1), two equivalent Pd(1), and four equivalent As(1) atoms to form a mixture of distorted corner, edge, and face-sharing PdTm6As4Pd2 cuboctahedra. As(1) is bonded in a 9-coordinate geometry to five equivalent Tm(1) and four equivalent Pd(1) atoms.
TmPdAs crystallizes in the orthorhombic Pnma space group. Tm(1) is bonded in a 11-coordinate geometry to six equivalent Pd(1) and five equivalent As(1) atoms. There are a spread of Tm(1)-Pd(1) bond distances ranging from 3.02-3.39 Å. There are three shorter (2.86 Å) and two longer (2.95 Å) Tm(1)-As(1) bond lengths. Pd(1) is bonded to six equivalent Tm(1), two equivalent Pd(1), and four equivalent As(1) atoms to form a mixture of distorted corner, edge, and face-sharing PdTm6As4Pd2 cuboctahedra. Both Pd(1)-Pd(1) bond lengths are 3.00 Å. There are a spread of Pd(1)-As(1) bond distances ranging from 2.58-2.82 Å. As(1) is bonded in a 9-coordinate geometry to five equivalent Tm(1) and four equivalent Pd(1) atoms.
