Materials Data on U3As2Se by Materials Project
U3As2Se is Heusler-like structured and crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded in a body-centered cubic geometry to six equivalent As and two equivalent Se atoms. All U–As bond lengths are 3.05 Å. Both U–Se bond lengths are 3.06 Å. In the second U site, U is bonded in a body-centered cubic geometry to five equivalent As and three equivalent Se atoms. There are a spread of U–As bond distances ranging from 3.03–3.06 Å. All U–Se bond lengths are 3.05 Å. As is bonded in a body-centered cubic geometry to eight U atoms. Se is bonded in a body-centered cubic geometry to eight U atoms.
