Thulium(II) fluoride is one of the fluoride salts of the lanthanide metal thulium, with the chemical compound of TmF2. It can react with zirconium tetrafluoride at 900 °C to form TmZrF6, which has a hexagonal structure.[1] In addition, low-temperature Mössbauer spectroscopy[2] and some theoretical studies[3] of thulium(II) fluoride have also been reported.
