The structure described by NdPrSb4 crystallizes in the monoclinic C2/m space group. Nd(1) is bonded in a 9-coordinate geometry to four equivalent Sb(1) and five equivalent Sb(3) atoms. Pr(1) is bonded in a 9-coordinate geometry to four equivalent Sb(1) and five equivalent Sb(2) atoms. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 8-coordinate geometry to two equivalent Nd(1), two equivalent Pr(1), and four equivalent Sb(1) atoms. In the second Sb site, Sb(2) is bonded in a 6-coordinate geometry to five equivalent Pr(1) and one Sb(2) atom. In the third Sb site, Sb(3) is bonded in a 6-coordinate geometry to five equivalent Nd(1) and one Sb(3) atom. is represented by the CIF file [CIF]
