Abstract

Single-phase ternary deuteride Li2BeD4 was synthesized by a high-pressure high-temperature technique from LiD and BeD 2. The crystal structure of Li2BeD4 was solved from X-ray and neutron powder diffraction data. The compound crystallizes in the monoclinic space group P21/c with lattice parameters a = 7.06228(9) Å, b = 8.3378(1) Å, c = 8.3465(1) Å, β =93.577(1)°, and Z = 8. Its structure contains isolated BeD4 tetrahedra and Li atoms that are located in the structure interstices. Li2BeD 4 does not undergo any structural phase transitions at temperatures down to 8 K.
