The material structure described by Ge is Hg_xSn structured and crystallizes in the orthorhombic Cmmm space group. Ge(1) is bonded to eight equivalent Ge(1) atoms to form a mixture of corner and edge-sharing GeGe8 hexagonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
