The compound described by GeBr2 is Rutile structured and crystallizes in the tetragonal P4_2/mnm space group. Ge(1) is bonded to six equivalent Br(1) atoms to form a mixture of edge and corner-sharing GeBr6 octahedra. The corner-sharing octahedral tilt angles are 47°. Br(1) is bonded in a distorted T-shaped geometry to three equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
