Materials Data on Nd2Bi by Materials Project
Nd2Bi crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Nd sites. In the first Nd site, Nd is bonded in a 4-coordinate geometry to four equivalent Nd and four equivalent Bi atoms. All Nd–Nd bond lengths are 3.29 Å. All Nd–Bi bond lengths are 3.44 Å. In the second Nd site, Nd is bonded to five equivalent Bi atoms to form a mixture of distorted corner and edge-sharing NdBi5 square pyramids. There are one shorter (3.31 Å) and four longer (3.37 Å) Nd–Bi bond lengths. Bi is bonded in a 9-coordinate geometry to nine Nd atoms.
