Synthesis and Crystal Structure of Lithium Beryllium Deuteride Li2BeD4. —
Single-phase ternary deuteride Li2BeD4 is synthesized by a high-pressure high-temperature technique from LiD and BeD2 (600 °C, 3 GPa, 1 h). The compound crystallizes
in the monoclinic space group P21/c with Z = 8 (powder X-ray and neutron diffraction).
The structure contains isolated BeD4 tetrahedra and Li atoms. Li2BeD4 does not undergo any structural phase transition at temperatures down to 8 K. — (BULYCHEV, B.
