Ge is BC8 structured and crystallizes in the trigonal R-3 space group. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one Ge(1) and three equivalent Ge(2) atoms to form corner-sharing GeGe4 trigonal pyramids. In the second Ge site, Ge(2) is bonded to one Ge(1) and three equivalent Ge(2) atoms to form corner-sharing GeGe4 trigonal pyramids.
Ge is BC8 structured and crystallizes in the trigonal R-3 space group. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one Ge(1) and three equivalent Ge(2) atoms to form corner-sharing GeGe4 trigonal pyramids. The Ge(1)-Ge(1) bond length is 2.56 Å. All Ge(1)-Ge(2) bond lengths are 2.53 Å. In the second Ge site, Ge(2) is bonded to one Ge(1) and three equivalent Ge(2) atoms to form corner-sharing GeGe4 trigonal pyramids. There is one shorter (2.50 Å) and two longer (2.54 Å) Ge(2)-Ge(2) bond lengths.
