In the second Ce site, Ce(2) is bonded in a 13-coordinate geometry to one Pd(5), two equivalent Pd(3), two equivalent Pd(4), four equivalent Pd(1), and four equivalent Pd(6) atoms. There are six inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 12-coordinate geometry to one Ce(1), two equivalent Ce(2), one Pd(1), one Pd(2), one Pd(3), one Pd(4), one Pd(6), two equivalent Pd(5), one Sn(1), and one Sn(2) atom. In the second Pd site, Pd(2) is bonded in a 12-coordinate geometry to three equivalent Ce(1), one Pd(1), one Pd(4), one Pd(5), three equivalent Pd(2), one Sn(1), and two equivalent Sn(2) atoms. In the third Pd site, Pd(3) is bonded in a 5-coordinate geometry to one Ce(1), two equivalent Ce(2), two equivalent Pd(1), two equivalent Pd(6), and two equivalent Sn(1) atoms. In the fourth Pd site, Pd(4) is bonded in a 3-coordinate geometry to two equivalent Ce(2), one Pd(5), two equivalent Pd(1), two equivalent Pd(2), two equivalent Pd(6), and two equivalent Sn(1) atoms.
