The material described by 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. is represented by the CIF card [CIF]
