SmPd2Si crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 11-coordinate geometry to ten equivalent Pd(1) and three equivalent Si(1) atoms. Pd(1) is bonded in a 12-coordinate geometry to five equivalent Sm(1), four equivalent Pd(1), and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to three equivalent Sm(1) and six equivalent Pd(1) atoms.
SmPd2Si crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 11-coordinate geometry to ten equivalent Pd(1) and three equivalent Si(1) atoms. There are a spread of Sm(1)-Pd(1) bond distances ranging from 2.98-3.56 Å. There is one shorter (3.03 Å) and two longer (3.05 Å) Sm(1)-Si(1) bond lengths.
