Molecular structure of germanium dibromide: A reinvestigation

The electron diffraction intensities of germanium dibromide [1] were reanalyzed based on computational evidence on the geometry of the excited state molecule. It was found that beside the ground state germanium dibromide molecule a small amount of iron dibromide, rather than other germanium dibromide species, may have been present in the vapor. The revised geometrical parameters of GeBr2 are: rg(Ge—Br) = 2.359 ± 0.005 A and ∠aBr—Ge—Br = 101.0 ± 0.3 A.
