Chemistry of chromium oxyfluorides and group VIB perfluoroglutarates

摘要

Pure chromium oxide trifluoride was prepared for the first time by reaction of CrO3 and ClF with subsequent multiple fluorine treatments at 120°c. On the basis of its infrared spectrum, the purple CrOF3 was assigned as a fluorine-bridged polymer with terminal oxygen groups. Chromium oxide trifluoride was found to be stable to 300°c, where it decomposes with the loss of oxygen to CrF3.
