Ge crystallizes in the tetragonal P4_32_12 space group. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent Ge(2) atoms to form distorted corner-sharing GeGe4 trigonal pyramids. In the second Ge site, Ge(2) is bonded in a rectangular see-saw-like geometry to two equivalent Ge(1) and two equivalent Ge(2) atoms.
Ge crystallizes in the tetragonal P4_32_12 space group. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent Ge(2) atoms to form distorted corner-sharing GeGe4 trigonal pyramids. All Ge(1)-Ge(2) bond lengths are 2.48 Å. In the second Ge site, Ge(2) is bonded in a rectangular see-saw-like geometry to two equivalent Ge(1) and two equivalent Ge(2) atoms. Both Ge(2)-Ge(2) bond lengths are 2.51 Å.
