All five actinide borohydrides are made by reaction of the anhydrous tetrafluoride with Al(BH/sub 4/)/sub 3/. Synthesis of Pa(BH/sub 4/)/sub 4/ is a modification of that of Th (BH/sub 4/)/sub 4/ by Hoekstra and Katz. The Np and Pu borohydrides were synthesized at O/sup 0/C, followed by cold trapping of the products at -78 and -196/sup 0/C. Physical properties of these borohydrides (color, stability, mp, vapor pressure, M/sup 4 +/ radius, structure, density, gas-phase infrared spectra) were compared with those of Th, U, and Hf borohydrides.
