The compound described by UPd2Sn crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 13-coordinate geometry to four equivalent Pd(1), four equivalent Pd(2), and five equivalent Sn(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 11-coordinate geometry to four equivalent U(1), two equivalent Pd(1), three equivalent Pd(2), and two equivalent Sn(1) atoms. In the second Pd site, Pd(2) is bonded in a 11-coordinate geometry to four equivalent U(1), three equivalent Pd(1), and four equivalent Sn(1) atoms. Sn(1) is bonded in a 11-coordinate geometry to five equivalent U(1), two equivalent Pd(1), and four equivalent Pd(2) atoms. is represented by the CIF card [CIF]
