Promethium(III) chloride, PmCl3, is the only known chloride of promethium. It is prepared (on a 100-µg scale) by reacting gaseous hydrogen chloride with promethium(III) oxide at 500 °C, and has the uranium trichloride structure with nine-coordinate promethium, isostructural with NdCl3 and SmCl3.[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.
