In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), one Cd(2), and two equivalent Cd(1) atoms. In the second Pt site, Pt(2) is bonded in a 9-coordinate geometry to one Ce(2), two equivalent Ce(1), two equivalent Cd(2), and four equivalent Cd(1) atoms. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 4-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), two equivalent Pt(1), and two equivalent Pt(2) atoms. In the second Cd site, Cd(2) is bonded in a 4-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), two equivalent Pt(1), and two equivalent Pt(2) atoms.
