The crystal structure described by Nd(SmSb)3 crystallizes in the cubic P2_13 space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. In the second Sm site, Sm(2) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. In the third Sm site, Sm(3) is bonded to six equivalent Sb(1) atoms to form distorted corner-sharing SmSb6 octahedra. The corner-sharing octahedral tilt angles are 48°. Nd(1) is bonded in a 6-coordinate geometry to six equivalent Sb(1) atoms. Sb(1) is bonded to two equivalent Sm(1), two equivalent Sm(2), two equivalent Sm(3), and two equivalent Nd(1) atoms to form a mixture of distorted edge, face, and corner-sharing SbNd2Sm6 hexagonal bipyramids. is represented by the CIF file [CIF]
