The material described by CePdTl crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 11-coordinate geometry to one Pd(2), four equivalent Pd(1), two equivalent Tl(2), and four equivalent Tl(1) atoms. In the second Ce site, Ce(2) is bonded in a 11-coordinate geometry to one Pd(2), four equivalent Pd(1), two equivalent Tl(2), and four equivalent Tl(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), one Tl(2), and two equivalent Tl(1) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to one Ce(2), two equivalent Ce(1), two equivalent Tl(2), and four equivalent Tl(1) atoms. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 10-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), two equivalent Pd(1), and two equivalent Pd(2) atoms. In the second Tl site, Tl(2) is bonded in a 10-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), two equivalent Pd(1), and two equivalent Pd(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
