This compound was first prepared by treating uranium tetrafluoride with aluminium borohydride: UF4 + 2 Al(BH4)3 → U(BH4)4 + 2 Al(BH4)F2 It may also be prepared by the solid-state reaction of uranium tetrachloride with lithium borohydride: UCl4 + 4 LiBH4 → U(BH4)4 + 4 LiCl Although solid U(BH4)4 is a polymer, it undergoes cracking, converting to the monomer.

Inorganic compound1
Uranium borohydride is the inorganic compound with the empirical formula U(BH4)4. (wikipedia.org)
Ligands1
Borohydrides are nonideal ligands for isotope separations, since there are isotopes of boron that occur naturally in high abundance: 10B (20%) and 11B (80%), while fluorine-19 is the only isotope of fluorine that occurs in nature in more than trace quantities. (wikipedia.org)
Sodium tetrahydroborate2
Sodium borohydride, also called sodium tetrahydridoborate and sodium tetrahydroborate, is an inorganic compound with the equation NaBH4. (alliedmarketresearch.com)

Boranes remained primarily of academic interest until World War II , when the U.S. government supported research to find volatile uranium compounds (borohydrides) for isotope separation, and the 1950s, when it supported programs to develop high-energy fuels for rockets and jet aircraft.
