Berkelium(III) fluoride is a binary inorganic compound of berkelium and fluorine with the chemical formula BkF
3.[1][2][3]
The compound can be prepared by treating Bk
2O
3 with a gaseous mixture of H
2 and HF at 600 °C.[4]
Berkelium trifluoride forms a yellow-green solid with two structures.[5] At low temperature, it is orthorhombic (YF
3 structure), with lattice parameters a = 670 pm, b = 709 pm, and c = 441 pm. At high temperature, it is trigonal (LaF
3 structure), with lattice parameters a = 697 pm and c = 714 pm. The transition temperature of BkF
3 is between 350 and 600 °C.[6][7]
Berkelium trifluoride is reduced by lithium to obtain metallic berkelium:
