MgNd2 crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a body-centered cubic geometry to two equivalent Nd(2) and six equivalent Nd(1) atoms. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 6-coordinate geometry to six equivalent Mg(1) and four equivalent Nd(2) atoms. In the second Nd site, Nd(2) is bonded in a 12-coordinate geometry to two equivalent Mg(1), four equivalent Nd(1), and six equivalent Nd(2) atoms.
MgNd2 crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a body-centered cubic geometry to two equivalent Nd(2) and six equivalent Nd(1) atoms. Both Mg(1)-Nd(2) bond lengths are 3.40 Å. There are two shorter (3.36 Å) and four longer (3.43 Å) Mg(1)-Nd(1) bond lengths. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 6-coordinate geometry to six equivalent Mg(1) and four equivalent Nd(2) atoms. There are two shorter (3.73 Å) and two longer (3.79 Å) Nd(1)-Nd(2) bond lengths. In the second Nd site, Nd(2) is bonded in a 12-coordinate geometry to two equivalent Mg(1), four equivalent Nd(1), and six equivalent Nd(2) atoms. There are four shorter (3.50 Å) and two longer (3.86 Å) Nd(2)-Nd(2) bond lengths.
