Gd2Ni2Mg crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a distorted square co-planar geometry to four equivalent Ni(1) atoms. Gd(1) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Gd(1), and one Ni(1) atom.
Gd2Ni2Mg crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a distorted square co-planar geometry to four equivalent Ni(1) atoms. All Mg(1)-Ni(1) bond lengths are 2.96 Å. Gd(1) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms. There are two shorter (2.87 Å) and four longer (2.88 Å) Gd(1)-Ni(1) bond lengths. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Gd(1), and one Ni(1) atom. The Ni(1)-Ni(1) bond length is 2.48 Å.
