Materials Data on USnPd2 by Materials Project
UPd2Sn crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. U is bonded in a 4-coordinate geometry to eight Pd and five equivalent Sn atoms. There are a spread of U–Pd bond distances ranging from 2.86–3.33 Å. There are a spread of U–Sn bond distances ranging from 3.17–3.35 Å. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 2-coordinate geometry to four equivalent U, five Pd, and two equivalent Sn atoms. There are a spread of Pd–Pd bond distances ranging from 2.78–3.18 Å. There are one shorter (2.67 Å) and one longer (2.84 Å) Pd–Sn bond lengths. In the second Pd site, Pd is bonded in a 11-coordinate geometry to four equivalent U, three equivalent Pd, and four equivalent Sn atoms. There are a spread of Pd–Sn bond distances ranging from 2.71–3.12 Å. Sn is bonded in a 11-coordinate geometry to five equivalent U and six Pd atoms.
