MgGe3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded to twelve equivalent Ge(1) atoms to form a mixture of face and corner-sharing MgGe12 cuboctahedra. Ge(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1) atoms.
MgGe3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded to twelve equivalent Ge(1) atoms to form a mixture of face and corner-sharing MgGe12 cuboctahedra. There are six shorter (2.97 Å) and six longer (3.10 Å) Mg(1)-Ge(1) bond lengths. Ge(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1) atoms.
