Promethium(III) fluoride, PmF3, is the only known fluoride of promethium. It is prepared (on a 100-µg scale) by reacting gaseous fluorine with promethium(III) oxide at 300 °C, and has the lanthanum trifluoride structure with eleven-coordinate promethium.[1]
Notes and references
Notes
- ↑ The molar mass is based on promethium-147 (t½ = 2.6234(2) a; Ar = 146.915 1385(26)),[2] the most commonly encountered isotope of promethium.
