Berkelium tetrafluoride is a binaryinorganic compound ofberkelium andfluorine with the chemical formulaBkF4.[1]
Berkelium tetrafluoride may be formed by the fluorination of berkelium trioxide, dioxide, or trifluoride with elemental fluorine at elevated temperatures:
Berkelium(IV) fluoride forms light brown crystals of monoclinic crystal structure ofuranium tetrafluoride type. Cell parameters: a = 1.2396 nm, b = 1.0466 nm, c = 0.8118 nm, angle β = 126.33°.[2][3]
Berkelium tetrafluoride is reduced bylithium at elevated temperatures to metallic berkelium:[4]
