Neutron‐diffraction studies on powered samples of BaLiH3 and BaLiD3 have shown that the structure is of the inverted perovskite type with the atomic positions of space group Pm3m: Ba in (0, 0, 0), Li in (12, 12, 12), and H or D in (12, 12, 0; 0, 12, 12; 12, 0, 12). The SrLiH3 and EuLiH3 are presumably isostructural. The lattice parameter for BaLiH3 is 4.023 ± 0.001 A and slightly smaller for BaLiD3. The total neutronscattering cross section for hydrogen is 30 ± 2 b, a rather low value compared to other hydrogen‐containing compounds, but comparable to that observed in other hydrides.
