The Molecular Structure of Hexachlorobenzene by Electron Diffraction

The non-planar structure of hexachlorobenzene is fairly suitable rather than the planar structure and the values of principal interatomic distances are &C-Cl=1.72±0.01 Å &C’-Cl=2.69±0.02 Å &Cl-Cl=3.15±0.02 Å They are in agreement with Hassel’s data. The author thinks that the re-investigation of the molecular structure of hexachlorobenzene by the precise sector method is necessary.
