Mixtures of calcium amide, Ca(NH2)(2) and uranium hydride,
UH3 were reacted at temperatures between 600 degreesC and 1000 degreesC for 2d to 30d. Starting
with a mixture 3 : I a single phase, black, microcrystalline product is obtained. As a result of
X-ray and neutron diffraction the phase has the composition (Ca0.75U0.25)N = Ca3UN4. It
crystallizes in the space group Fm3m with a = 4.9398 (1) Angstrom in the sodium chloride
structure type with statistical occupation of the cation site 4a by 3Ca and 1U.
