Materials Data on U3Pt by Materials Project
U3Pt is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded to four equivalent U and four equivalent Pt atoms to form a mixture of distorted face, edge, and corner-sharing UU4Pt4 tetrahedra. All U–U bond lengths are 2.94 Å. All U–Pt bond lengths are 2.94 Å. In the second U site, U is bonded in a 8-coordinate geometry to eight equivalent U and six equivalent Pt atoms. All U–Pt bond lengths are 3.39 Å. Pt is bonded in a distorted body-centered cubic geometry to fourteen U atoms.
