The structure of room temperature PuGa has been determined. The material has a body‐centered tetragonal lattice, space group I 4 mm (No. 107), Z = 8, a = 6.6408 ± 12, c = 8.0833 ± 20 Å, and a calculated density of 11.50 Mg m −3 . Intensity data was obtained from a powder‐pattern film taken with Cr Kα radiation, λ = 2.2909 Å. The structure, which deviates slightly from an ideal subcell, was refined by least‐squares calculation to R 1 = 0.079 using 39 observed reflections. Pu–Pu distances range from 3.08 to 3.40 Å, Pu–Ga distances from 3.07 to 3.26 Å, and Ga–Ga distances from 2.75 to 3.89 Å.
