Materials Data on GeF2 by Materials Project
GeF2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Ge2+ is bonded in a rectangular see-saw-like geometry to four F1- atoms. There are a spread of Ge–F bond distances ranging from 1.89–2.31 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two equivalent Ge2+ atoms. In the second F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Ge2+ atoms.
