Photochemical Synthesis of Tungsten Pentafluoride, WF5

다국어 초록 (Multilingual Abstract)

A new synthetic route for the synthesis of WF5 utilizing a mercury photosensitized reduction of tungsten hexafluoride with H2 is described. Crystals of WF5 were studied using single‐crystal X‐ray diffraction, resulting in the first‐reported crystal structure of WF5. Powder X‐ray diffraction studied at room‐temperature showed the compound was phase‐pure. The IR spectrum of WF5 was reinvestigated and interpreted with the use of solid‐state quantum‐chemical calculations using the DFT‐PBE0 density functional method. The compound synthesized herein was free of HF and moisture but may have contained minute amounts of WOF4, that were only observed in the IR spectrum.
