Mg2CdGe crystallizes in the triclinic P1 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 8-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), and four equivalent Cd(1) atoms. Both Mg(1)-Mg(1) bond lengths are 3.20 Å. There is one shorter (2.39 Å) and one longer (2.74 Å) Mg(1)-Mg(2) bond length. There are a spread of Mg(1)-Cd(1) bond distances ranging from 2.78-3.24 Å. In the second Mg site, Mg(2) is bonded in a 8-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), and four equivalent Ge(1) atoms. Both Mg(2)-Mg(2) bond lengths are 3.20 Å. There are a spread of Mg(2)-Ge(1) bond distances ranging from 2.69-3.31 Å. Cd(1) is bonded in a 6-coordinate geometry to four equivalent Mg(1) and two equivalent Ge(1) atoms. There is one shorter (2.37 Å) and one longer (2.71 Å) Cd(1)-Ge(1) bond length. Ge(1) is bonded in a 5-coordinate geometry to four equivalent Mg(2) and two equivalent Cd(1) atoms.
