2004 Beryllium I 1100 51- 022 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. M.; SHPANCHENKO*, R. V.; ANTIPOV, E. V.; SHEPTYAKOV, D. V.; BUSHMELEVA, S. N.; BALAGUROV, A.
