The material described by GeF2 crystallizes in the orthorhombic P2_12_12_1 space group. Ge(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent F(1) and two equivalent F(2) atoms. There are two inequivalent F sites. In the first F site, F(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ge(1) atoms. In the second F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent Ge(1) atoms. is represented by the CIF card [CIF]
