NdPtSb crystallizes in the hexagonal P6_3mc space group. Nd(1) is bonded to six equivalent Pt(1) and six equivalent Sb(1) atoms to form a mixture of distorted face and edge-sharing NdSb6Pt6 cuboctahedra. Pt(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three equivalent Sb(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three equivalent Pt(1) atoms.
NdPtSb crystallizes in the hexagonal P6_3mc space group. Nd(1) is bonded to six equivalent Pt(1) and six equivalent Sb(1) atoms to form a mixture of distorted face and edge-sharing NdSb6Pt6 cuboctahedra. There are three shorter (3.14 Å) and three longer (3.53 Å) Nd(1)-Pt(1) bond lengths. There are three shorter (3.28 Å) and three longer (3.38 Å) Nd(1)-Sb(1) bond lengths. Pt(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three equivalent Sb(1) atoms. All Pt(1)-Sb(1) bond lengths are 2.65 Å. Sb(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three equivalent Pt(1) atoms.
