NdPtIn3 crystallizes in the cubic Pm-3n space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a cuboctahedral geometry to twelve equivalent In(1) atoms. In the second Nd site, Nd(2) is bonded in a 16-coordinate geometry to four equivalent Pt(1) and twelve equivalent In(1) atoms. Pt(1) is bonded in a 6-coordinate geometry to three equivalent Nd(2) and six equivalent In(1) atoms. In(1) is bonded in a 2-coordinate geometry to one Nd(1), three equivalent Nd(2), and two equivalent Pt(1) atoms.
NdPtIn3 crystallizes in the cubic Pm-3n space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a cuboctahedral geometry to twelve equivalent In(1) atoms. All Nd(1)-In(1) bond lengths are 3.47 Å. In the second Nd site, Nd(2) is bonded in a 16-coordinate geometry to four equivalent Pt(1) and twelve equivalent In(1) atoms. All Nd(2)-Pt(1) bond lengths are 3.49 Å. There are eight shorter (3.42 Å) and four longer (3.48 Å) Nd(2)-In(1) bond lengths. Pt(1) is bonded in a 6-coordinate geometry to three equivalent Nd(2) and six equivalent In(1) atoms. All Pt(1)-In(1) bond lengths are 2.72 Å.
