Materials Data on U3Cd by Materials Project
U3Cd 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 in a distorted body-centered cubic geometry to four equivalent U and four equivalent Cd atoms. All U–U bond lengths are 3.01 Å. All U–Cd bond lengths are 3.01 Å. In the second U site, U is bonded in a 8-coordinate geometry to eight equivalent U and six equivalent Cd atoms. All U–Cd bond lengths are 3.48 Å. Cd is bonded in a distorted body-centered cubic geometry to fourteen U atoms.
