Plutonium(III) fluoride or plutonium trifluoride is the

trigonal prismatic.[3]

Reactions

A plutonium(III) fluoride precipitation method has been investigated as an alternative to the typical plutonium peroxide method of recovering plutonium from solution, such as that from a nuclear reprocessing plant.[4] A 1957 study by the Los Alamos National Laboratory reported a less effective recovery than the traditional method,[5] while a more recent study sponsored by the United States Office of Scientific and Technical Information found it to be one of the more effective methods.[6]

Plutonium(III) fluoride can be used for manufacture of the

plutonium-gallium alloy
instead of more difficult to handle metallic plutonium.
