Materials Data on LiNp3 by Materials Project
LiNp3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Li is bonded in a distorted body-centered cubic geometry to fourteen Np atoms. There are eight shorter (2.74 Å) and six longer (3.17 Å) Li–Np bond lengths. There are two inequivalent Np sites. In the first Np site, Np is bonded in a 4-coordinate geometry to four equivalent Li and four equivalent Np atoms. All Np–Np bond lengths are 2.74 Å. In the second Np site, Np is bonded in a 8-coordinate geometry to six equivalent Li and eight equivalent Np atoms.
