Ce3Pd5Si crystallizes in the orthorhombic Imma space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 11-coordinate geometry to two equivalent Pd(2), eight equivalent Pd(1), and one Si(1) atom. In the second Ce site, Ce(2) is bonded in a 11-coordinate geometry to two equivalent Pd(2), eight equivalent Pd(1), and one Si(1) atom. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 11-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), one Pd(2), three equivalent Pd(1), and one Si(1) atom. In the second Pd site, Pd(2) is bonded in a 2-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), four equivalent Pd(1), and two equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to one Ce(2), two equivalent Ce(1), two equivalent Pd(2), and four equivalent Pd(1) atoms.
