Gd2MgGe2 crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a square co-planar geometry to four equivalent Ge(1) atoms. Gd(1) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Gd(1), and one Ge(1) atom.
Gd2MgGe2 crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a square co-planar geometry to four equivalent Ge(1) atoms. All Mg(1)-Ge(1) bond lengths are 2.90 Å. Gd(1) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. There are two shorter (2.98 Å) and four longer (3.09 Å) Gd(1)-Ge(1) bond lengths. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Gd(1), and one Ge(1) atom. The Ge(1)-Ge(1) bond length is 2.52 Å.
