Nd2Ni2Mg crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded to eight equivalent Nd(1) and four equivalent Ni(1) atoms to form a mixture of distorted face and corner-sharing MgNd8Ni4 cuboctahedra. Nd(1) is bonded in a 6-coordinate geometry to four equivalent Mg(1) and six equivalent Ni(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Nd(1), and one Ni(1) atom.
Nd2Ni2Mg crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded to eight equivalent Nd(1) and four equivalent Ni(1) atoms to form a mixture of distorted face and corner-sharing MgNd8Ni4 cuboctahedra. All Mg(1)-Nd(1) bond lengths are 3.37 Å. All Mg(1)-Ni(1) bond lengths are 3.00 Å. Nd(1) is bonded in a 6-coordinate geometry to four equivalent Mg(1) and six equivalent Ni(1) atoms. There are two shorter (2.93 Å) and four longer (2.95 Å) Nd(1)-Ni(1) bond lengths. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Nd(1), and one Ni(1) atom. The Ni(1)-Ni(1) bond length is 2.47 Å.
