The crystal structure described by Nd2Sb crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to five equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing NdSb5 trigonal bipyramids. In the second Nd site, Nd(2) is bonded in a 4-coordinate geometry to four equivalent Sb(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Nd(2) and five equivalent Nd(1) atoms. is represented by the CIF card [CIF]
