Sm2MgGe2 crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a square co-planar geometry to four equivalent Ge(1) atoms. Sm(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 Sm(1), and one Ge(1) atom.
Sm2MgGe2 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 2.93 Å. Sm(1) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. There are two shorter (3.01 Å) and four longer (3.12 Å) Sm(1)-Ge(1) bond lengths. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Sm(1), and one Ge(1) atom. The Ge(1)-Ge(1) bond length is 2.53 Å.
