The determination of the structures of the hexafluorides of sulfur, selenium and tellurium by the electron diffraction method

The application of electron diffraction methods in the study of gas molecules was first made by Mark and Wierl,(1) who investigated the structure of a large number of molecules in this way. Using methods closely similar to theirs, and briefly discussed in the following paragraphs, we have determined the atomic configuration and interatomic distances in SF6, SeF6 and TeF6
