The crystal structure described by Ge is diamond-like structured and crystallizes in the hexagonal P6_3/mmc 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 tetrahedra. In the second Ge site, Ge(2) is bonded to one Ge(2) and three equivalent Ge(1) atoms to form corner-sharing GeGe4 tetrahedra. is represented by the CIF card [CIF]
