Ge is Clathrate-like structured and crystallizes in the cubic Fd-3m space group. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent Ge(2) atoms to form corner-sharing GeGe4 tetrahedra. In the second Ge site, Ge(2) is bonded to one Ge(1) and three equivalent Ge(3) atoms to form corner-sharing GeGe4 tetrahedra. In the third Ge site, Ge(3) is bonded to one Ge(2) and three equivalent Ge(3) atoms to form corner-sharing GeGe4 tetrahedra.
Ge is Clathrate-like structured and crystallizes in the cubic Fd-3m space group. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent Ge(2) atoms to form corner-sharing GeGe4 tetrahedra. All Ge(1)-Ge(2) bond lengths are 2.43 Å. In the second Ge site, Ge(2) is bonded to one Ge(1) and three equivalent Ge(3) atoms to form corner-sharing GeGe4 tetrahedra. All Ge(2)-Ge(3) bond lengths are 2.46 Å. In the third Ge site, Ge(3) is bonded to one Ge(2) and three equivalent Ge(3) atoms to form corner-sharing GeGe4 tetrahedra. There are two shorter (2.46 Å) and one longer (2.48 Å) Ge(3)-Ge(3) bond length.
