The material structure described by Nd2Bi crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 8-coordinate geometry to four equivalent Nd(1) and four equivalent Bi(1) atoms. In the second Nd site, Nd(2) is bonded to five equivalent Bi(1) atoms to form a mixture of distorted edge and corner-sharing NdBi5 square pyramids. Bi(1) is bonded in a 9-coordinate geometry to four equivalent Nd(1) and five equivalent Nd(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
