Mg Mg Cd Ge
MgCdMgGe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgCd cluster and one MgGe cluster. In the MgCd cluster, Mg(1) is bonded in a 1-coordinate geometry to one Cd(1) atom. The Mg(1)-Cd(1) bond length is 0.45 Å. Cd(1) is bonded in a single-bond geometry to one Mg(1) atom. In the MgGe cluster, Mg(2) is bonded in a single-bond geometry to one Ge(1) atom. The Mg(2)-Ge(1) bond length is 0.06 Å. Ge(1) is bonded in a distorted single-bond geometry to one Mg(2) atom.
