Pd3Si is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Pd sites. In the first Pd site, Pd(2) is bonded in a bent 120 degrees geometry to two equivalent Si(1) atoms. In the second Pd site, Pd(1) is bonded in a 3-coordinate geometry to three equivalent Si(1) atoms. Si(1) is bonded in a 8-coordinate geometry to two equivalent Pd(2) and six equivalent Pd(1) atoms.
Pd3Si is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Pd sites. In the first Pd site, Pd(2) is bonded in a bent 120 degrees geometry to two equivalent Si(1) atoms. There is one shorter (2.36 Å) and one longer (2.38 Å) Pd(2)-Si(1) bond length. In the second Pd site, Pd(1) is bonded in a 3-coordinate geometry to three equivalent Si(1) atoms. There are a spread of Pd(1)-Si(1) bond distances ranging from 2.36-2.57 Å. Si(1) is bonded in a 8-coordinate geometry to two equivalent Pd(2) and six equivalent Pd(1) atoms.
