Materials Data on Li3Np by Materials Project

Li3Np crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Li is bonded in a 10-coordinate geometry to six equivalent Li and four equivalent Np atoms. There are two shorter (2.88 Å) and four longer (2.99 Å) Li–Li bond lengths. There are two shorter (3.24 Å) and two longer (3.25 Å) Li–Np bond lengths. Np is bonded to twelve equivalent Li atoms to form a mixture of face and corner-sharing NpLi12 cuboctahedra.

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.
