The compound described by NdOs4Sb12 crystallizes in the cubic Im-3 space group. Nd(1) is bonded to twelve equivalent Sb(1) atoms to form NdSb12 cuboctahedra that share faces with eight equivalent Os(1)Sb6 octahedra. Os(1) is bonded to six equivalent Sb(1) atoms to form OsSb6 octahedra that share corners with six equivalent Os(1)Sb6 octahedra and faces with two equivalent Nd(1)Sb12 cuboctahedra. The corner-sharing octahedral tilt angles are 55°. Sb(1) is bonded in a 5-coordinate geometry to one Nd(1), two equivalent Os(1), and two equivalent Sb(1) atoms. is represented by the CIF file [CIF]
