Ce7Pd3 crystallizes in the orthorhombic Cmc2_1 space group. There are five inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 3-coordinate geometry to one Pd(1) and two equivalent Pd(2) atoms. In the second Ce site, Ce(2) is bonded in a 3-coordinate geometry to two equivalent Pd(1) and two equivalent Pd(2) atoms. In the third Ce site, Ce(3) is bonded in a 3-coordinate geometry to one Pd(1) and three equivalent Pd(2) atoms. In the fourth Ce site, Ce(4) is bonded in a 2-coordinate geometry to four equivalent Pd(2) atoms. In the fifth Ce site, Ce(5) is bonded in a 2-coordinate geometry to two equivalent Pd(1) and two equivalent Pd(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to one Ce(1), two equivalent Ce(2), two equivalent Ce(3), and four equivalent Ce(5) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to one Ce(1), one Ce(2), two equivalent Ce(4), two equivalent Ce(5), and three equivalent Ce(3) atoms.
